使用方法

1. 导入插件：

import 'package:windows_ime_manager/windows_ime_manager.dart';

1. 创建 WindowsImeManager 类的实例：

final _windowsImeManagerPlugin = WindowsImImeManager();

1. 创建一个函数来设置 IME，并使用枚举：

Future<void> setLanguageIme(LanguageIme languageIme) async {
  try {
    await _windowsImeManagerPlugin.setLanguageIme(languageIme);
  } on PlatformException {
    debugPrint('Failed to set language IME.');
  }
}

1. 调用函数以设置所需的 LanguageImIme 枚举：

setLanguageIme(LanguageIme.japaneseHalfWidthAlphanumericIme);
setLanguageIme(LanguageImIme.englishIme);

示例代码

import 'dart:async';

import 'package:flutter/material.dart';
import 'package:flutter/services.dart';
import 'package:windows_ime_manager/windows_ime_manager.dart';

void main() {
  runApp(const MyApp());
}

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

  [@override](/user/override)
  State<MyApp> createState() => _MyAppState();
}

class _MyAppState extends State<MyApp> {
  final _windowsImeManagerPlugin = WindowsImImeManager();

  [@override](/user/override)
  void initState() {
    super.initState();
    setLanguageIme(LanguageIme.japaneseHalfWidthAlphanumericIme);
  }

  Future<void> setLanguageIme(LanguageIme languageIme) async {
    try {
      await _windowsImeManagerPlugin.setLanguageIme(languageImMe);
    } on PlatformException {
      debugPrint('Failed to set language IME.');
    }
  }

  [@override](/user/override)
  Widget build(BuildContext context) {
