SelectableText maxLines should behave the same as Text

[cruvie]

Steps to Reproduce

1. run main.dart

Expected results:
if the text less than 10 lines , SelectableText should just wrap the text in lines that the text really needs
Actual results:
SelectableText make the text line as maxLine even the text doesn't need

Code sample

import 'package:flutter/material.dart';

Future<void> main() async {
  return runApp(const MyApp());
}

class MyApp extends StatefulWidget {
  const MyApp({super.key});

  @override
  State<MyApp> createState() => _MyAppState();
}

class _MyAppState extends State<MyApp> {
  @override
  Widget build(context) {
    return const MaterialApp(
      home: PageHome(),
    );
  }
}

class PageHome extends StatefulWidget {
  const PageHome({Key? key}) : super(key: key);

  @override
  State<PageHome> createState() => _PageHomeState();
}

class _PageHomeState extends State<PageHome> {
  final GlobalKey<NavigatorState> homeNavigatorKey = GlobalKey();

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        title: const Text('Home'),
      ),
      body: Container(
          color: Colors.green,
          child: const SelectableText(
            style: TextStyle(fontSize: 20, color: Colors.black),
            "eeeeeeeeeee",
            maxLines: 10,
          )),
    );
  }
}

SelectableText is based on EditableText, so it behaves the same as TextField (screenshot below). Even though you're right, it probably makes more sense for it to behave like Text.

You might want to use SelectionArea here instead of SelectableText, which I believe will eventually replace SelectableText (see #104547).

@justinmc yes that a little counterintuitive ,and I have already replaced it to SelectionArea

[justinmc]

Sounds good. Let's keep this issue open since I think it is a real bug, though likely SelectableText will be deprecated before it is fixed.
