Blocked input on Samsung devices

[Flaviu Pasca]

The code below blocks input on Samsung phones:

final mmTextController = MoneyMaskedTextController(
decimalSeparator: DecimalSeparator,
thousandSeparator: ThousandSeparator,
precision: precision,
);
mmTextController.afterChange = (String maskedValue, double rawValue) {
// the line below blocks any further input on Samsung phones
mmTextController.selection = TextSelection.collapsed(offset: mmTextController.text.length);
};

Hey! I have a similar problem. :(

Only in Samsung devices, when trying update the mask, keyboard freezes

I did a example.

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

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

class MyApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      title: 'Flutter Demo',
      theme: ThemeData(
        primarySwatch: Colors.blue,
      ),
      home: MyHomePage(title: 'Flutter Demo Home Page'),
    );
  }
}

class MyHomePage extends StatefulWidget {
  MyHomePage({Key key, this.title}) : super(key: key);

  final String title;

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

class _MyHomePageState extends State<MyHomePage> {
  MaskedTextController _controller;

  @override
  void initState() {
    _controller = MaskedTextController(mask: "[phone]", text: "");
    super.initState();
  }

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        title: Text(widget.title),
      ),
      body: Center(
        child: Column(
          mainAxisAlignment: MainAxisAlignment.center,
          children: <Widget>[
            TextField(
              keyboardType: TextInputType.number,
              controller: _controller,
              onChanged: (newValue) {
                if (newValue.length >= 15) {
                  _controller.updateMask("(00) 00000-0000");
                } else {
                  _controller.updateMask("[phone]");
                }
                _controller.updateText(newValue);
              },
            ),
          ],
        ),
      ),
    );
  }
}

[Giuliano Stravini]

I found this issue on Flutter Github.

@Giuliano-Stravini hi, I have the same problem (on Samsung Note 8). I'm using Flutter Channel stable, v1.17.0

If I use TextFormField without MoneyMaskedTextController, it will be okay. How can MoneyMaskedTextController cause the lagging? Do you know?

Have you fixed your problem yet?
