Another exception was thrown: A RenderFlex overflowed by 99456 pixels on the bottom.
Minimal code to reproduce this is:
import 'package:flutter/material.dart';
import 'package:xterm/xterm.dart';
import 'package:xterm/flutter.dart';
void main() {
runApp(const MyApp());
}
class MyApp extends StatelessWidget {
const MyApp({Key? key}) : super(key: key);
@override
Widget build(BuildContext context) {
return MaterialApp(
title: 'Flutter Demo',
theme: ThemeData(
primarySwatch: Colors.teal,
),
home: const MyHomePage(),
);
}
}
class MyHomePage extends StatefulWidget {
const MyHomePage({Key? key}) : super(key: key);
@override
State<MyHomePage> createState() => _MyHomePageState();
}
class _MyHomePageState extends State<MyHomePage> {
final terminal = Terminal(
maxLines: 10000,
);
@override
Widget build(BuildContext context) {
return Scaffold(
appBar: AppBar(
title: const Text("Hello, terminal!"),
),
body: Center(
child: Column(
mainAxisAlignment: MainAxisAlignment.start,
children: <Widget>[
TerminalView(
terminal: terminal,
style: const TerminalStyle(fontFamily: ['Cascadia Mono']),
),
],
),
),
);
}
}
Have you tried putting an Expanded widget around TerminalView:
Expanded(
child: TerminalView(
terminal: terminal
style: const TerminalStyle(fontFamily: ['Cascadia Mono']),
),
)
