In #107006, this issue has been marked as resolved since v3.1.0 but this issue is still reproduced in v3.3.10.
Tested in Hebrew using a TextField and a TextFormField

Steps to Reproduce

  1. Execute flutter run on the code sample
  2. Write in Hebrew or any other RTL language in the text field.
  3. Tap on any place to change the cursor position then tap again at the end of the text field, the cursor position will change to the penultimate character

Expected results:
The cursor position should be after the last character.

Actual results:
The cursor position moves to the penultimate character.

Code sample 
import 'package:flutter/material.dart';
import 'package:flutter_localizations/flutter_localizations.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',
      locale: const Locale("he"),
      localizationsDelegates: const [
        GlobalMaterialLocalizations.delegate,
        GlobalWidgetsLocalizations.delegate,
        GlobalCupertinoLocalizations.delegate,
      ],
      supportedLocales: const [Locale("he")],
      theme: ThemeData(
        primarySwatch: Colors.blue,
      ),
      home: const MyHomePage(title: 'Flutter Demo Home Page'),
    );
  }
}

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

  final String title;

  @override
  State<MyHomePage> createState() => _MyHomePageState();
}

class _MyHomePageState extends State<MyHomePage> {
  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        title: Text(widget.title),
      ),
      body: const Center(
        child: Padding(
          padding: EdgeInsets.all(16),
          child: TextField(),
        ),
      ),
    );
  }
}

    ✗ CocoaPods installed but not working.
        You appear to have CocoaPods installed but it is not working.
        This can happen if the version of Ruby that CocoaPods was installed with is different from the one being used to invoke it.
        This can usually be fixed by re-installing CocoaPods.
