Answer 1

嗯，我试图解决它，我所做的是：

*1.-重新安装颤振

2.-重新安装Dart SDK

6.-复制年级末尾的下一行。properties

android.useAndroidX=true
android.enableJetifier=true

7.-文件app\build.gradle的更改

android {
    compileSdkVersion 28

...

defaultConfig {
    minSdkVersion 21
    targetSdkVersion 28
    multiDexEnabled true
    ...
}

}

subprojects {
    ...
    gradle.projectsEvaluated {
        tasks.withType(JavaCompile) {
            options.compilerArgs << "-Xlint:deprecation" << "-Xlint:unchecked"
        }
    }
}

flutter clean
