Flutter 开发 Cannot run with sound null safety解决方案

初次开发Flutter，初次使用Flutter第三方库（english_words）如下：

dependencies:
  flutter:
    sdk: flutter
   cupertino_icons: ^1.0.2
   english_words: ^3.1.5

结果：一跑报下面错

Launching lib\main.dart on Redmi K30 5G in debug mode...
Running Gradle task 'assembleDebug'...
Error: Cannot run with sound null safety, because the following dependencies
don't support null safety:

 - package:english_words

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


FAILURE: Build failed with an exception.

* Where:
Script 'D:\flutter\sdk\flutter\packages\flutter_tools\gradle\flutter.gradle' line: 1070

* What went wrong:
Execution failed for task ':app:compileFlutterBuildDebug'.
> Process 'command 'D:\flutter\sdk\flutter\bin\flutter.bat'' finished with non-zero exit value 1

解决方法如下：
第一步：
在AndroidStudio->Run->Edit Configurations

第二步：在Additional run args 填入命令：--no-sound-null-safety

再运行就不会再报错了！
