windows配置flutter 遇到的问题及解决办法

1）Android license status unknown.

[!] Android toolchain - develop for Android devices (Android SDK 28.0.3)
X Android license status unknown.

使用flutter doctor --android-licenses命令

2）A newer version of the Android SDK is required. To update, run:

A newer version of the Android SDK is required. To update, run:
android-sdk\tools\bin\sdkmanager --update

按命令执行更新，如果出现错误，请保证你的java版本大于1.8（java8）

这步骤耗时比较久

如果遇到Warning: An error occurred during installation: Failed to move away or delete existing target file: D:\android-sdk\tools
Move it away manually and try again..
done

把sdk下tools文件夹命名为tool，执行android-sdk\tool\bin\sdkmanager --update（ps：tools下的.install文件夹非常大，可以移动到执行命令后自建tools目录下，节省下载时间）

完成后，再执行flutter doctor --android-licenses

3）Android Studio配置

[√] Android Studio (version 3.2)
X Flutter plugin not installed; this adds Flutter specific functionality.
X Dart plugin not installed; this adds Dart specific functionality.

参考：https://flutterchina.club/get-started/editor/#androidsstudio

安装Dart和Flutter插件

4）执行Initializing gradle...非常慢

主要是google maven仓库被墙。进入flutter sdk的目录，修改flutter/packages/flutter_toolsgradle/flutter.gradle文件

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:3.2.1'
}
}

项目里Android下的build.gradle文件

//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' }

5）Downloading gradle-4.10.2-all.zip失败

Finished with error: ProcessException: Process "gradlew.bat" exited abnormally:
Downloading https://services.gradle.org/distributions/gradle-4.10.2-all.zip

Exception in thread "main" javax.net.ssl.SSLException: Connection has been shutdown: javax.net.ssl.SSLException: java.net.SocketException: Connection reset

修改配置为：

distributionUrl=file:///D:/gradle/gradle-4.10.2-all.zip
