flutter_ime

A Flutter plugin for controlling Windows IME (Input Method Editor) state. This plugin helps you manage keyboard input modes in Windows applications, particularly useful for login forms and password fields where English input is preferred.

Features

• Switch to English keyboard mode programmatically on Windows
• Check current keyboard input mode
• Automatic IME mode switching for password fields
• Pure Windows API implementation with no external dependencies

Getting started

Add this to your package's pubspec.yaml file:

dependencies:
  flutter_ime: ^1.0.0

Usage

import 'package:flutter_ime/flutter_ime.dart';

// Create an instance
final flutterIme = FlutterIme();

// Switch to English keyboard
await flutterIme.setEnglishKeyboard();

// Check if current keyboard is English
bool isEnglish = await flutterIme.isEnglishKeyboard();

Automatic Password Field Example

class LoginPage extends StatefulWidget {
  @override
  _LoginPageState createState() => _LoginPageState();
}

class _LoginPageState extends State<LoginPage> {
  final _flutterIme = FlutterIme();
  final _passwordFocusNode = FocusNode();

  @override
  void initState() {
    super.initState();
    
    // Switch to English keyboard when password field gets focus
    _passwordFocusNode.addListener(() {
      if (_passwordFocusNode.hasFocus) {
        _flutterIme.setEnglishKeyboard();
      }
    });
  }

  @override
  Widget build(BuildContext context) {
    return TextField(
      focusNode: _passwordFocusNode,
      obscureText: true,
      decoration: InputDecoration(
        labelText: 'Password',
      ),
    );
  }
}
