Text flickering #46
Description
Steps to Reproduce
The bug is caused by the inability to set a text size, when two AutoSizeText with the same AutoSizeTextGroup with certain parameters (as in sample code) are horizontally next to each other. Depending on the screen size, this results in a sort of text size flickering (in reality this flickering is much much faster, but the GIF has a low FPS).
The sample code is an app, to reproduce the bug just run it.
As mentioned above, to reproduce the bug on a specific screen size, the text length of the longest line in one of the AutoSizeTexts may need to be changed.
Code sample
import 'package:auto_size_text/auto_size_text.dart';
import 'package:flutter/material.dart';
void main() => runApp(MyApp());
class MyApp extends StatelessWidget {
// This widget is the root of your application.
@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> {
AutoSizeGroup group;
@override
void initState() {
group = AutoSizeGroup();
super.initState();
}
@override
Widget build(BuildContext context) {
return Scaffold(
appBar: AppBar(
title: Text(widget.title),
),
body: Center(
child: Row(
mainAxisAlignment: MainAxisAlignment.center,
children: <Widget>[
Expanded(
child: Card(
child: AutoSizeText(
'You have\npushed the\nbutton this\nmanyn times:aa',
group: group,
style: TextStyle(fontSize: 50),
maxLines: 4,
)
)
),
