Flutter 创建项目就报错 Gradle7.3.0网络下载问题

前提

最后这些都是建议在安装了 Flutter 的包，还有 android sdk 包的环境下

gradel 7.3.0的错误

Flutter assets will be downloaded from https://storage.flutter-io.cn. Make sure you trust this source!
Launching lib\main.dart on BAL AL80 in debug mode...
* What went wrong:
Plugin [id: 'com.android.application', version: '7.3.0', apply: false] was not found in any of the following sources:
- Gradle Core Plugins (plugin is not in 'org.gradle' namespace)
- Included Builds (None of the included builds contain this plugin)
- Plugin Repositories (could not resolve plugin artifact 'com.android.application:com.android.application.gradle.plugin:7.3.0')
  Searched in the following repositories:
    Google
    MavenRepo
    Gradle Central Plugin Repository

解决方法

1. 退出当前项目
2. 

   //但其实核心是有这个，但我找不到了

   

3.解决后就新建的项目就没有这个问题了

错误2

这个错误是我在添加了 video_player 的flutter 插件后出现的，当时我人也是无语死了，加个插件就错误

//下载的 Java JDK环境配置，选择下载.zip包，不推荐.exe,我下了还是报错，后面改.zip就不会了，坑
