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
- 退出当前项目
-
//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
JAVA JDK安装地址
教程自行去找跟配置
