当运行flutter项目时，【解决如下报错】

前提：你可以上google

如你再次运行时遇到

WARNING: [Processor] Library 'C:\Users\luich\.gradle\caches\modules-2\files-2.1\androidx.media2\media2-session\1.2.1\f927563711e36371c19b2e86fb7ccf1c3f259ca4\media2-session-1.2.1.aar' contains references to both AndroidX and old support library. This seems like the library is partially migrated. Jetifier will try to rewrite the library anyway.Example of androidX reference: 'androidx/media2/session/MediaBrowser$Builder'Example of support library reference: 'android/support/v4/media/session/MediaSessionCompat$Token'

这个警告是关于 media2-session 库中同时存在 AndroidX 和旧版 support library 的引用。这通常与音频相关的功能有关。让我们解决这个问题：
首先检查你的项目是否真的需要 media2-session。在 pubspec.yaml 中查找相关依赖：

dependencies:vector_math: ^2.1.4win32: ^5.10.0# 检查是否有音频相关的依赖

在 android/app/build.gradle 中确保正确配置 AndroidX：

# 添加
dependencies {implementation "androidx.media2:media2-session:1.2.1"
}
# 添加defaultConfig {// TODO: Specify your own unique Application ID (https://developer.android.com/studio/build/application-id.html).applicationId "com.luichun.luichun"// You can update the following values to match your application needs.// For more information, see: https://docs.flutter.dev/deployment/android#reviewing-the-gradle-build-configuration.minSdkVersion flutter.minSdkVersiontargetSdkVersion flutter.targetSdkVersionversionCode flutterVersionCode.toInteger()versionName flutterVersionName# 添加android.useAndroidX=true# 添加android.enableJetifier=true}
