After change minSdkVersion from 16 to 19 on old android devices eg. Android 5.1.1, Android 6 I install app but can't load data from web rest api. On Android 11 all work fine.

I'm change version because some plugin need min sdk 19.

Which android version my app now supports?

android {
        compileSdkVersion 30
        defaultConfig {
            applicationId "com.example.test"
            minSdkVersion 19
            targetSdkVersion 30
        }

My sdk manager: enter image description here

Console log when run app on Android 6 emulator.

In main.dart file I'm add:

import 'dart:io';

class MyHttpOverrides extends HttpOverrides{
  @override
  HttpClient createHttpClient(SecurityContext? context){
    return super.createHttpClient(context)
      ..badCertificateCallback = (X509Certificate cert, String host, int port)=> true;
  }
}


--Add before runApp(MyApp());
HttpOverrides.global = MyHttpOverrides();
runApp(MyApp());
