flutter debug&release 已解决 Error: Cannot run with sound null safety, because the following depende...

flutter sdk 版本升级到2.0或者更高的版本后就发现运行时会报错：

Error: Cannot run with sound null safety, because the following dependencies
don't support null safety:

 - package:loading_indicator_view
 - package:flutter_swiper
 - package:flutter_page_indicator
 - package:transformer_page_view

For solutions, see https://dart.dev/go/unsound-null-safety


FAILURE: Build failed with an exception.

也就是说以上有些包不支持 safety模式。

解决方案：--no-sound-null-safety

1. 方案一：

通过命令行运行:

• run （debug运行）
  flutter run --no-sound-null-safety
• build （打包apk）
  flutter build apk --no-sound-null-safety

2. 方案二:

• 也可以在Android studio中设置运行配置。首先打开Edit Configurations 页面；

• 然后在Additional run args 这行键入一下命令:
