flutter:修改flutter的Android的minSdkVersion(Flutter 3.29.2)

 一，报错信息

Your project is configured with Android NDK 26.3.11579264, but the following plugin(s) depend on a different Android NDK version:
- audioplayers_android requires Android NDK 27.0.12077973
- flutter_sound requires Android NDK 27.0.12077973
- path_provider_android requires Android NDK 27.0.12077973
Fix this issue by using the highest Android NDK version (they are backward compatible).
Add the following to /Users/liuhongdi/StudioProjects/demo3/android/app/build.gradle.kts:

    android {
        ndkVersion = "27.0.12077973"
        ...
    }

/Users/liuhongdi/StudioProjects/demo3/android/app/src/debug/AndroidManifest.xml Error:
	uses-sdk:minSdkVersion 21 cannot be smaller than version 24 declared in library [:flutter_sound] /Users/liuhongdi/StudioProjects/demo3/build/flutter_sound/intermediates/merged_manifest/debug/processDebugManifest/AndroidManifest.xml as the library might be using APIs not available in 21
	Suggestion: use a compatible library with a minSdk of at most 21,
		or increase this project's minSdk version to at least 24,
		or use tools:overrideLibrary="xyz.canardoux.fluttersound" to force usage (may lead to runtime failures)

二，解决:

进入安装目录，例如:

/Users/liuhongdi/soft/flutter/packages/flutter_tools/gradle/src/main/groovy

编辑:

vi flutter.groovy

如下:

  50     /** Sets the minSdkVersion used by default in Flutter app projects. */
  51     //public  final int minSdkVersion = 21
  52     public  final int minSdkVersion = 24

指定 public  final int minSdkVersion 的值为 24
