PS D:\F\luichun> flutter run

当运行flutter项目时，【解决如下报错】

/C:/flutter/packages/flutter/lib/src/painting/star_border.dart:530:27: Error: The getter 'Matrix4' isn't defined for the class '_StarGenerator'.
 - '_StarGenerator' is from 'package:flutter/src/painting/star_border.dart' ('/C:/flutter/packages/flutter/lib/src/painting/star_border.dart').
Try correcting the name to the name of an existing getter, or defining a getter or field named 'Matrix4'.
    squashMatrix.multiply(Matrix4.translationValues(-rect.center.dx, -rect.center.dy, 0));

# 2. 获取新依赖
PS D:\F\luichun> flutter pub get

# 3. 运行项目
PS D:\F\luichun> flutter run

开启本地windows的开发者选项

   start ms-settings:developers

在这里插入图片描述

运行项目

flutter run

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: ^2.1.4
  win32: ^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.minSdkVersion
        targetSdkVersion flutter.targetSdkVersion
        versionCode flutterVersionCode.toInteger()
        versionName flutterVersionName
        # 添加
        android.useAndroidX=true
        # 添加
        android.enableJetifier=true
    }
