7. 采用自定义无边框窗口、托盘图标

项目结构目录

Flutter3-WinSeek客户端ai项目已经更新到我的原创作品集。

flutter3.32+deepseek+dio客户端ai流式对话Exe

通过 flutter create flutter_winseek 命令即可快速创建一个flutter空项目模板。
通过 flutter run -d windows 命令即可运行到windows桌面。

.env环境变量配置

在flutter中使用 flutter_dotenv 插件来配置环境变量。

# 项目名称
APP_NAME = 'Flutter3-WinSeek'

# DeepSeek API配置
DEEPSEEK_API_KEY = apikey
DEEPSEEK_BASE_URL = https://api.deepseek.com

在页面获取环境变量

// 获取.env环境变量baseUrl和apiKey
String baseURL = dotenv.get('DEEPSEEK_BASE_URL');
String apiKEY = dotenv.get('DEEPSEEK_API_KEY');

项目布局模板

项目整体分为侧边栏+自定义顶部导航+AI聊天对话区三个模块。

flutter3集成deepseek api流输出

flutter通过dio请求deepseek对话大模型，实现stream流式输出打字。

final response = await dio.post(
  '$baseURL/v1/chat/completions',
  options: Options(
    // 响应超时
    receiveTimeout: const Duration(seconds: 60),
    headers: {
      "Content-Type": "application/json",
      "Authorization": "Bearer $apiKEY",
    },
    // 设置响应类型为流式响应
    responseType: ResponseType.stream,
  ),
  data: {
    // 多轮会话
    'messages': widget.multiConversation ? chatStore.historySession : [{'role': 'user', 'content': editorValue}],
    'model': 'deepseek-chat', // deepseek-chat对话模型 deepseek-reasoner推理模型
    'stream': true, // 流式输出
    'max_tokens': 8192, // 限制一次请求中模型生成 completion 的最大 token 数(默认使用 4096)
    'temperature': 0.4, // 严谨采样 越低越严谨(默认1)
  }
);

flutter3自定义托盘管理

项目中采用 system_tray 组件来自定义系统托盘图标。

// 创建系统托盘图标
Future<void> initSystemTray() async {
  String trayIco = 'assets/images/tray.ico';
  SystemTray systemTray = SystemTray();

  // 初始化系统托盘
  await systemTray.initSystemTray(
    title: 'system-tray',
    iconPath: trayIco,
  );

  // 右键菜单
  final Menu menu = Menu();
  await menu.buildFrom([
    MenuItemLabel(label: '打开主界面', image: 'assets/images/tray.ico', onClicked: (menuItem) async => await windowManager.show()),
    MenuItemLabel(label: '隐藏窗口', image: 'assets/images/tray.ico', onClicked: (menuItem) async => await windowManager.hide()),
    MenuItemLabel(label: '设置中心', image: 'assets/images/tray.ico', onClicked: (menuItem) => Get.toNamed('/setting')),
    MenuItemLabel(label: '锁屏', image: 'assets/images/tray.ico', onClicked: (menuItem) => {}),
    MenuItemLabel(label: '关闭程序并退出', image: 'assets/images/tray.ico', onClicked: (menuItem) async => await windowManager.destroy()),
  ]);
  await systemTray.setContextMenu(menu);

  // 右键事件
  systemTray.registerSystemTrayEventHandler((eventName) async {
    debugPrint('eventName: $eventName');
    if (eventName == kSystemTrayEventClick) {
      Platform.isWindows ? await windowManager.show() : systemTray.popUpContextMenu();
    } else if (eventName == kSystemTrayEventRightClick) {
      Platform.isWindows ? systemTray.popUpContextMenu() : await windowManager.show();
    }
  });
}
