推荐答案

我建议您启用AndroidX.

I suggest you to enable AndroidX.

官方文档: https://flutter.dev/docs/开发/packages-and-plugins/androidx-compatibility

如您在第三项中所看到的:

As you see in third entry:

在android/gradle.properties中，附加=>

In android/gradle.properties, append =>

android.enableJetifier=true
android.useAndroidX=true

如果您不想使用AndroidX，则可以使用下面列出的最新版本的软件包.

If you don't want to use AndroidX, latest version of packages you can use listed down below.

如果您的软件包未在此处列出，则只能选择启用AndroidX.

If your package don't listed there, enabling AndroidX is only choice.

还可以更改android/app/gradle.build中的最小sdk:

Also change your minimum sdk inside android/app/gradle.build:

    defaultConfig {
        // TODO: Specify your own unique Application ID (https://developer.android.com/studio/build/application-id.html).
        applicationId "com.example.flutter_testing"
        minSdkVersion 16 // => Make this 21
        targetSdkVersion 28
        versionCode flutterVersionCode.toInteger()
        versionName flutterVersionName
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
    }

最后，请遵循该答案:

也更改gradle版本.

Change the gradle version also.
