配置开发环境Android studio

先安装flutter源码,再安装Android studio zip版本
设置镜像环境变量,Mac/Linux直接执行命令,win下添加环境变量,win需要安装Git for Windows,先设置这两个环境变量

export PUB_HOSTED_URL=https://pub.flutter-io.cn
export FLUTTER_STORAGE_BASE_URL=https://storage.flutter-io.cn
CHROME_EXECUTABLE =C:\Program Files (x86)\Microsoft\Edge\Application\msedge.exe edge路径
flutter config --enable-windows-desktop 启动桌面支持

安装flutter和Dart插件

1 . JAVA_HOME环境变量设置 C:\app\jetbrains\goland-2023.1.2.win\jbr

2. ANDROID_HOME环境变量 C:\app\jetbrains\sdk
   path设置 %JAVA_HOME%\bin
   %ANDROID_HOME%\platform-tools
   %ANDROID_HOME%\build-tools\34.0.0

3. path设置 C:\app\flutter\bin 然后运行flutter doctor
   flutter不能是快捷方式，找到android studio目录下面jre，下载openjdk解压到里面用goland下面jbr也可以。

• 检测显示 Android license status unknown
  需要在android studio中安装SDK Tools里面command-line Tools
  运行 flutter doctor --android-licenses 一路yes
• 安装Android SDK,连上安卓手机下载对应sdk,在真机上测试,小米在设置-我的设备-全部参数-MIUI版本单机7次进入开发模式
  flutter卡在Installing build\app\outputs\flutter-apk\app.apk,用下面方法解决
  卸载后安装不了 卸载应用,在sdk目录platform-tools下执行 adb uninstall com.example.srsw
• 编译错误

1. 可能修改：
   flutter/packages/flutter_tools/gradle/下面
   resolve_dependencies.gradle aar_init_script.gradle flutter.gradle,这三个文件中
   https://storage.googleapis.com/download.flutter.io 不可用时用镜像(http://download.flutter.io)
2. 项目Android下面build.gradle文件中修改
   allprojects {
   repositories {

    google()
    mavenCentral()
    maven { url 'https://storage.googleapis.com/download.flutter.io' } //新增这一行即可

   }
   }
   如果还是不能编译 前两个方法可替换为
   maven { url ‘https://maven.aliyun.com/repository/google' }
   maven { url ‘https://maven.aliyun.com/repository/central' }
   maven { url ‘https://maven.aliyun.com/repository/public' }
   打包程序
   flutter build apk -t lib/main.dart
   flutter build ios -t lib/main.dart
