Flutter蓝牙通信插件bluetooth_deneme的使用

bluetooth_deneme

这是一个新的Flutter项目。

开始使用

此项目是一个Flutter插件包的起点，属于一种专门的包，包含针对Android和/或iOS的平台特定实现代码。

对于Flutter开发的帮助，请查看官方文档，其中提供了教程、示例、移动开发指南以及完整的API参考。

示例代码

以下是bluetooth_deneme插件的完整示例代码：

import 'package:flutter/material.dart';
import 'dart:async';
import 'package:flutter/services.dart';
import 'package:bluetooth_deneme/bluetooth_deneme.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> {
  // 用于存储蓝牙状态的变量
  String _bluetoothState = 'Unknown';

  // 初始化蓝牙插件实例
  final _bluetoothDenemePlugin = BluetoothDeneme();

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

  // 启用蓝牙
  Future<void> enableBluetooth() async {
    String bluetoothState;
    try {
      bluetoothState = await _bluetoothDenemePlugin.enableBluetooth() ?? 
          'Unknown bluetooth state';
    } on PlatformException {
      bluetoothState = 'Failed to enable bluetooth.';
    }
    if (!mounted) return;

    setState(() {
      _bluetoothState = bluetoothState;
    });
  }

  // 禁用蓝牙
  Future<void> disableBluetooth() async {
    String bluetoothState;
    try {
      bluetoothState = await _bluetoothDenemePlugin.disableBluetooth() ?? 
          'Unknown bluetooth state';
    } on PlatformException {
      bluetoothState = 'Failed to disable bluetooth.';
    }
    if (!mounted) return;

    setState(() {
      _bluetoothState = bluetoothState;
    });
  }

  // 获取已配对设备列表
  Future<void> getBondedDevices() async {
    String bluetoothState;
    try {
      bluetoothState = await _bluetoothDenemePlugin.getBondedDevices() ?? 
          'Unknown bluetooth state';
    } on PlatformException {
      bluetoothState = 'Failed to disable bluetooth.';
    }
    if (!mounted) return;

    setState(() {
      _bluetoothState = bluetoothState;
    });
  }

  // 开始蓝牙扫描
  Future<void> startScan() async {
    String bluetoothState;
    try {
      bluetoothState = await _bluetoothDenemePlugin.startScan() ?? 
          'Unknown bluetooth state';
    } on PlatformException {
      bluetoothState = 'Failed to disable bluetooth.';
    }
    if (!mounted) return;

    setState(() {
      _bluetoothState = bluetoothState;
    });
  }

  // 连接蓝牙设备
  Future<void> connectDevice() async {
    String bluetoothState;
    try {
      bluetoothState = await _bluetoothDenemePlugin.connectDevice() ?? 
          'Unknown bluetooth state';
    } on PlatformException {
      bluetoothState = 'Failed to disable bluetooth.';
    }
    if (!mounted) return;

    setState(() {
      _bluetoothState = bluetoothState;
    });
  }

  // 打印测试数据
  Future<void> printTest(Map<String, String> args) async {
    String bluetoothState;
    try {
      bluetoothState = await _bluetoothDenemePlugin.printTest(args) ?? 
          'Unknown bluetooth state';
    } on PlatformException {
      bluetoothState = 'Failed to disable bluetooth.';
    }
  }
