Flutter 报错：AndroidManifest.xml 文件未找到 - 解决方法

This error typically occurs when the Flutter build process is unable to find the AndroidManifest.xml file in the expected location. Here are a few steps you can try to resolve this issue:

1. Check the location of the AndroidManifest.xml file in your Flutter project. It should be located at 'android/app/src/main/AndroidManifest.xml'. Make sure the file exists at this location.

2. If the AndroidManifest.xml file does not exist at the expected location, you can try running the following command in your project directory to recreate it:

   flutter create .
   

   This command will recreate the necessary Android project files, including the AndroidManifest.xml file.

3. If the AndroidManifest.xml file exists at the correct location but the error persists, try cleaning the project and rebuilding it. You can do this by running the following commands:

   flutter clean
   flutter build apk
   

   This will clean any cached build artifacts and rebuild the project, potentially resolving any issues with the AndroidManifest.xml file.

If none of these steps work, you may need to provide more information about your project setup and any additional error messages you are encountering in order to troubleshoot further.
