onInit handler is not called on initialisation

[kaboc]

onInit is called from didUpdateWidget(), which is called only on rebuild, resulting in it not getting called on initialisation.

I just tried the example, but it's working. It's called on initialization

Here is the minimum code.

import 'package:flutter/material.dart';
import 'package:country_code_picker/country_code_picker.dart';

void main() => runApp(MyApp());

class MyApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    print('build');

    return MaterialApp(
      home: Scaffold(
        body: Center(
          child: CountryCodePicker(
            initialSelection: 'US',
            onInit: print,
          ),
        ),
      ),
    );
  }
}

If it is true that onInit is called on initialisation, it should prints "build" and then "+1", but actually it does only when "build" is output more than once by rebuilds as the results of hot reloads/restarts or of other causes.

Additionally, would you try the following code as well please? It does not print "didUpdateWidget", which means didUpdateWidget is not called on initialisation.
As this code does not depend on third party packages, you can run it on DartPad too.

import 'package:flutter/material.dart';

void main() => runApp(MyApp());

class MyApp extends StatefulWidget {
  MyApp();

  @override
  _MyAppState createState() => _MyAppState();
}

class _MyAppState extends State<MyApp> {

  @override
  void initState() {
    super.initState();
    print('initState');
  }

  @override
  void didUpdateWidget(MyApp oldWidget) {
    super.didUpdateWidget(oldWidget);
    print('didUpdateWidget');
  }

  @override
  Widget build(BuildContext context) {
    return const SizedBox.shrink();
  }
}

I can swear that the minimum code part prints "+1"

Anyway I believe that there is a problem, I'll analyze it better

#74 fixes this bug

Thank you! 😄
