I suggest you to enable AndroidX.

Official docs: https://flutter.dev/docs/development/packages-and-plugins/androidx-compatibility

As you see in third entry:

In android/gradle.properties, append =>

android.enableJetifier=true
android.useAndroidX=true

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

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

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"
    }

And finally, follow that answer:

How to fix "Execution failed for task ':app:processDebugResources'. > Android resource linking failed"[Android/Flutter]

Change the gradle version also.
