当运行flutter项目时，【办理如下报错】

条件：你可以上google

如你再次运行时遇到

1. 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.
2. Example of androidX reference: 'androidx/media2/session/MediaBrowser$Builder'
3. Example of support library reference: 'android/support/v4/media/session/MediaSessionCompat$Token'

复制代码

这个告诫是关于 media2-session 库中同时存在 AndroidX 和旧版 support library 的引用。这通常与音频相干的功能有关。让我们办理这个题目：
起首查抄你的项目是否真的须要 media2-session。在 pubspec.yaml 中查找相干依赖：

1. dependencies:
2.   vector_math: ^2.1.4
3.   win32: ^5.10.0
4.   # 检查是否有音频相关的依赖

复制代码

在 android/app/build.gradle 中确保精确设置 AndroidX：

1. # 添加
2. dependencies {
3.     implementation "androidx.media2:media2-session:1.2.1"
4. }
5. # 添加
6.     defaultConfig {
7.         // TODO: Specify your own unique Application ID (https://developer.android.com/studio/build/application-id.html).
8.         applicationId "com.luichun.luichun"
9.         // You can update the following values to match your application needs.
10.         // For more information, see: https://docs.flutter.dev/deployment/android#reviewing-the-gradle-build-configuration.
11.         minSdkVersion flutter.minSdkVersion
12.         targetSdkVersion flutter.targetSdkVersion
13.         versionCode flutterVersionCode.toInteger()
14.         versionName flutterVersionName
15.         # 添加
16.         android.useAndroidX=true
17.         # 添加
18.         android.enableJetifier=true
19.     }
