Problem with "multi_image_picker" in dart

Question

I have the problem with library minSdk: Suggestion: use a compatible library with a minSdk of at most 16, or increase this project's minSdk version to at least 19 I Changed the build.gradle in the section minSdkVersion but show this:

D8: Program type already present: android.support.v4.app.INotificationSideChannel$Stub

FAILURE: Build failed with an exception.

What went wrong: Execution failed for task ':app:transformDexArchiveWithExternalLibsDexMergerForDebug'.

    defaultConfig {
        // TODO: Specify your own unique Application ID (https://developer.android.com/studio/build/application-id.html).
        applicationId "com.example.prueba_2"
        minSdkVersion 19
        targetSdkVersion 28
        versionCode flutterVersionCode.toInteger()
        versionName flutterVersionName
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
    }

This plugin was migrated from using the deprecated Android Support Library to AndroidX. If your project was migrated to use it as well you should install version 4.X.X of the plugin. If you are using the old project structure please use version 2.4.11

I still had the error , so i tried the solution in this link (using the selected answer) :
