三、问题

3.1、升级Flutter 版本。

localhost:AndroidGo hailuwang$ flutter --version
Flutter 1.17.1 • channel unknown • unknown source
Framework • revision f7a6a7906b (3 weeks ago) • 2020-05-12 18:39:00 -0700
Engine • revision 6bc433c6b6
Tools • Dart 2.8.2

3.2、`git clone` 之后，需要更改 `./flutter_demo/.android/local.properties` 中环境变量信息

sdk.dir=/Users/hailuwang/Library/Android/sdk
flutter.sdk=/Users/hailuwang/tools/flutter

flutter_demo 工程，如果遇到问题，需要先行编译，编译命令：

flutter --no-color packages get

3.2、已适配androidx，Flutter 环境，需要更新到最新，建议更换Flutter 的更新源，配置如下：

{flutterRoot}/flutter/packages/flutter_tools/gradle/flutter.gradle

 buildscript {
     repositories {
-        google()
-        jcenter()
+maven { url 'https://maven.aliyun.com/repository/google' }
+maven { url 'https://maven.aliyun.com/repository/jcenter' }
+maven { url 'http://maven.aliyun.com/nexus/content/groups/public' }
     }
     dependencies {
         classpath 'com.android.tools.build:gradle:3.5.0'
