【解决方案1】：

这是 SDK 与插件兼容性的问题

转到您的 build.grade 文件并检查这些：

android {
    compileSdkVersion 30 // must be 30 for compatibility

    defaultConfig {
        applicationId "tv.digicash"
        minSdkVersion 23
        targetSdkVersion 30
        versionCode flutterVersionCode.toInteger()
        versionName flutterVersionName
        testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"
    }

在 Android Studio 中的文件 > 项目结构（项目和 SDK 左侧菜单）中检查这些内容

他们必须在 30 岁或以上
