Flutter环境搭建踩坑过程

Flutter安装

1、将如下环境变量加入到用户环境变量中：

PUB_HOSTED_URL=https://pub.flutter-io.cn
FLUTTER_STORAGE_BASE_URL=https://storage.flutter-io.cn

2、获取Flutter SDK

去flutter官网下载其最新可用的安装包，点击下载 ；

3、重启Windows以应用此更改（必须，不重启会有坑）

4、重启完毕，CMD 运行

 flutter doctor

[-] Android toolchain - develop for Android devices
    • Android SDK at D:\Android\sdk
    * Android SDK is missing command line tools; download from https://goo.gl/XxQghQ
    • Try re-installing or updating your Android SDK,
      visit https://flutter.io/setup/#android-setup for detailed instructions.

根据实际检测结果做相应处理

Flutter安装 Android license status unknown 解决方案

执行命令：

flutter doctor --android-licenses

Android Studio安装

1、下载并安装 Android Studio
2、启动Android Studio，然后执行“Android Studio安装向导”。这将安装最新的Android SDK，Android SDK平台工具和Android SDK构建工具，这是Flutter为Android开发时所必需的
3、在settings->plugins里搜索并安装flutter插件，安装flutter同时会安装dart插件（要梯子）
4、创建模拟器（要梯子）
5、在flutter安装目录下找到 pacakges/flutter_tools_/gradle,做以下修改
①修改/packages/flutter_tools/gradle/flutter.gradle文件

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' }
		maven {
     url 'http://download.flutter.io'}
    }

把

private static final String MAVEN_REPO = "https://storage.googleapis.com/download.flutter.io";

改为

private static final String MAVEN_REPO = "https://storage.flutter-io.cn/download.flutter.io";

如图：

②修改/packages/flutter_tools/gradle/resolve_dependencies.gradle文件

repositories {
    
    //google()
	//jcenter()
	maven {
     url 'http://download.flutter.io'}
}

至此，完成Flutter环境搭建。
