Style Guide

Lint

  • Official Dart lint rules - The Dart linter is a static analyzer for identifying possible problems in your Dart source code. More than a hundred linter rules are available, checking anything from potential typing issues, coding style, and formatting. This package, lints, contains the lint settings recommended by the Dart team.

  • import_sorter - 🎯 Dart package to automatically organize your dart imports. Any dart project supported! Will sorts imports alphabetically and then group them in the following order:

    1. Dart imports
    2. Flutter imports
    3. Package imports
    4. Project imports
  • flutter-surf-lint-rules

Community

  • fluttercommunity - A central place for all community made Flutter packages. To get started, see the README of the 'community' repository.

  • fluttercandies - Custom Flutter Candies (packages) for you to build your Flutter app easily. Enjoy it!

Starter Samples

Architecture:

  • Event Bus - A simple Event Bus using Dart Streams for decoupling applications.

  • mvc_pattern - Flutter Plugin to implement one of many variations of the MVC design pattern.

Add Flutter to existing app

  • 💗💗👍👍 [email protected] - A next-generation Flutter-Native hybrid solution. FlutterBoost is a Flutter plugin which enables hybrid integration of Flutter for your existing native apps with minimum efforts.The philosophy of FlutterBoost is to use Flutter as easy as using a WebView. Managing Native pages and Flutter pages at the same time is non-trivial in an existing App. FlutterBoost takes care of page resolution for you. The only thing you need to care about is the name of the page(usually could be an URL).
  • flutter_thrio @hellobike
  • Faraday - Flutter plugin for integrate flutter to existing app

Navigation & Routing

  • 💗🤔👀 fluro - The brightest, hippest, coolest router for Flutter.
  • flutter_favorite_badge chopper - Chopper is an http client generator for Dart and Flutter using source_gen and inspired by Retrofit.
  • flutter_favorite_badge - A Flutter package to help you handle your application routing and synchronize it with browser URL. Beamer uses the power of Router and implements all the underlying logic for you.
  • flutter_favorite_badge go_router - The purpose of the go_router package is to use declarative routes to reduce complexity, regardless of the platform you're targeting (mobile, web, desktop), handle deep and dynamic linking from Android, iOS and the web, along with a number of other navigation-related scenarios, while still (hopefully) providing an easy-to-use developer experience.
  • flow_builder - Flutter Flows made easy!

Data & Backend

  • RxDart - RxDart extends the capabilities of Dart Streams and StreamControllers.

    Dart comes with a very decent Streams API out-of-the-box; rather than attempting to provide an alternative to this API, RxDart adds functionality from the reactive extensions specification on top of it.

    RxDart does not provide its Observable class as a replacement for Dart Streams. Instead, it offers several additional Stream classes, operators (extension methods on the Stream class), and Subjects.

    If you are familiar with Observables from other languages, please see the Rx Observables vs. Dart Streams comparison chart for notable distinctions between the two.

  • flutter_favorite_badge Google! json_serializable - Provides Dart Build System builders for handling JSON. The builders generate code when they find members annotated with classes defined in package:json_annotation.

    To generate to/from JSON code for a class, annotate it with JsonSerializable. You can provide arguments to JsonSerializable to configure the generated code. You can also customize individual fields by annotating them with JsonKey and providing custom arguments. See the table below for details on the annotation values.

    To generate a Dart field with the contents of a file containing JSON, use the JsonLiteral annotation.

  • dart_json_mapper - This package allows programmers to annotate Dart objects in order to Serialize / Deserialize them to / from JSON.

Storage

  • 🔥 Feature rich: Drift has builtin support for transactions, schema migrations, complex filters and expressions, batched updates and joins. We even have a builtin IDE for SQL!

  • 📦 Modular: Thanks to builtin support for daos and imports in sql files, drift helps you keep your database code simple.

  • 🛡️ Safe: Drift generates typesafe code based on your tables and queries. If you make a mistake in your queries, drift will find it at compile time and provide helpful and descriptive lints.

  • ⚡ Fast: Even though drift lets you write powerful queries, it can keep up with the performance of key-value stores like shared preferences and Hive. Drift is the only major persistence library with builtin threading support, allowing you to run database code across isolates with zero additional effort. Reactive: Turn any sql query into an auto-updating stream! This includes complex queries across many tables

  • ⚙️ Cross-Platform support: Drift works on Android, iOS, macOS, Windows, Linux and the web. This template is a Flutter todo app that works on all platforms.

  • 🗡️ Battle tested and production ready: Drift is stable and well tested with a wide range of unit and integration tests. It powers production Flutter apps. With drift, persistence on Flutter is fun!

    To start using drift, read our detailed docs.

    • Non-destructive performance
  • getx - GetX is an extra-light and powerful solution for Flutter. It combines high-performance state management, intelligent dependency injection, and route management quickly and practically. GetX has 3 basic principles. This means that these are the priority for all resources in the library: PRODUCTIVITY, PERFORMANCE AND ORGANIZATION.

  • flutter_favorite_badge provider - A wrapper around InheritedWidget to make them easier to use and more reusable.

    By using provider instead of manually writing InheritedWidget, you get:

    • simplified allocation/disposal of resources
    • lazy-loading
    • a vastly reduced boilerplate over making a new class every time
    • devtool friendly – using Provider, the state of your application will be visible in the Flutter devtool
    • a common way to consume these InheritedWidgets (See Provider.of/Consumer/Selector)
    • increased scalability for classes with a listening mechanism that grows exponentially in complexity (such as ChangeNotifier, which is O(N) for dispatching notifications).
  • river_pod - A state-management library that:

    • catches programming errors at compile time rather than at runtime
    • removes nesting for listening/combining objects
    • ensures that the code is testable

    This project can be considered as a rewrite of provider to make improvements that would be otherwise impossible.

    For learning how to use Riverpod, see its documentation: https://riverpod.dev

  • flutter_favorite_badge mobx - MobX is a state-management library that makes it simple to connect the reactive data of your application with the UI. This wiring is completely automatic and feels very natural. As the application-developer, you focus purely on what reactive-data needs to be consumed in the UI (and elsewhere) without worrying about keeping the two in sync.

    It's not really magic but it does have some smarts around what is being consumed (observables) and where (reactions), and automatically tracks it for you. When the observables change, all reactions are re-run. What's interesting is that these reactions can be anything from a simple console log, a network call to re-rendering the UI.

    MobX has been a very effective library for the JavaScript apps and this port to the Dart language aims to bring the same levels of productivity.

  • get_it - This is a simple Service Locator for Dart and Flutter projects with some additional goodies highly inspired by Splat. It can be used instead of InheritedWidget or Provider to access objects e.g. from your UI.

  • Flutter Official packages pigeon - Pigeon is a code generator tool to make communication between Flutter and the host platform type-safe, easier and faster.

  • flutter_favorite_badge freezed - another code generator for unions/pattern-matching/copy. Using Freezed, we will get:

    • a simple and concise syntax for defining models, where we don't need to define both a constructor and a property. Instead, we only need to define the constructor, removing unnecessary duplication.

    • a copyWith method, for cloning objects with different values. Note: As opposed to many alternatives, when using Freezed, that copyWith method correctly supports assigning null to a value.

    • union-types/pattern matching, for making impossible states impossible. See also unions/sealed-classes.

    • an automatic serialization/deserialization of your objects (including union types).

    • a default ==/toString implementation which respectively compares/shows all properties of the object.

    See the example for a preview on what's available

  • json_to_dart - Given a JSON string, this library will generate all the necessary Dart classes to parse and generate JSON.

    This library is designed to generate Flutter friendly model classes following the flutter's doc recommendation.

  • flutter_gen - The Flutter code generator for your assets, fonts, colors, … — Get rid of all String-based APIs.

    Inspired by SwiftGen.

  • flutter_favorite_badge google/built_value - Built Value provides:

    • Immutable value types;
    • EnumClass, classes that behave like enums;
    • JSON serialization.
    • Immutable collections are from built_collection.

    See the API docs.

  • Dart Official Build - These packages provide libraries for generating, compiling and serving Dart code.

    • build: Defines the interfaces for creating a Builder which is a way of doing codegen that is compatible across build systems (pub, bazel, standalone runner).

      For packages doing code generation this should generally be the only package against which there is a public dependency. Packages may have a dev_dependency on one or more of the other packages.

    • build_config: Support for parsing build.yaml files. Used by build_runner.

    • build_modules: Support for discovering the sub-modules within packages and creating summaries of those modules. Used by build_web_compilers but should not be used directly by most users.

    • build_resolvers: An implementation of the Resolver interface to use the analyzer during build steps.

    • build_runner: Provides utilities to enact builds and a way to automatically run builds based on configuration.

      This package should generally be a dev_dependency as it is used to run standalone builds. The only exception would be wrapping the build and watch methods with some other package.

    • build_test: Stub implementations for classes in Build and some utilities for running instances of builds and checking their outputs.

      This package generally only be a dev_dependency as it introduces a dependency on package:test. The exception to that would be if you were creating another testing-only package that wraps this one.

    • build_web_compilers: Provides the dart2js and dartdevc support for your package. To use this package you should add it as a dev_dependency.

      If you are using the automated build scripts, your project will automatically start being compiled with dartdevc, and you can start developing with chrome without any configuration.

  • dart-lang/source_gen - source_gen provides utilities for automated source code generation for Dart:

    • A framework for writing Builders that consume and produce Dart code.
    • A convention for human and tool generated Dart code to coexist with clean separation, and for multiple code generators to integrate in the same project.

    Its main purpose is to expose a developer-friendly API on top of lower-level packages like the analyzer or build. You don't have to use source_gen in order to generate source code; we also expose a set of library APIs that might be useful in your generators.

    • is sitting in the project root folder
    • strictly follows the Keep a Changelog v1.0.0 format
    • uses basic markdown (no HTML and complex formatting supported)

Monitor

  • dart-lang/stack_trace - This library provides the ability to parse, inspect, and manipulate stack traces produced by the underlying Dart implementation. It also provides functions to produce string representations of stack traces in a more readable format than the native StackTrace implementation.

    Traces can be parsed from native StackTraces using Trace.from, or captured using Trace.current. Native StackTraces can also be directly converted to human-readable strings using Trace.format.
