✅ |
使用方法
首先,导入 catch_device_type
包:
import 'package:catch_device_type/my_plugin.dart';
然后,实例化 DeviceInfoPlugin
类并使用 Android 获取器来获取特定平台的设备信息。
Future<void> initPlatformState() async {
bool? platformVersion;
try {
platformVersion = await MyPlugin.platformVersion ?? false;
} on PlatformException {
debugPrint('Failed to get platform version.');
}
if (!mounted) return;
setState(() {
_platformVersion = platformVersion ?? false;
});
}
示例代码
以下是一个完整的示例代码,展示如何在 Flutter 应用中使用该插件来检测设备类型。
import 'package:catch_device_type/my_plugin.dart';
import 'package:flutter/material.dart';
import 'dart:async';
import 'package:flutter/services.dart';
void main() {
runApp(const MyApp());
}
class MyApp extends StatefulWidget {
const MyApp({Key? key}) : super(key: key);
[@override](/user/override)
State<MyApp> createState() => _MyAppState();
}
class _MyAppState extends State<MyApp> {
bool _platformVersion = false;
[@override](/user/override)
void initState() {
super.initState();
initPlatformState();
}
// Platform messages are asynchronous, so we initialize in an async method.
Future<void> initPlatformState() async {
bool? platformVersion;
// Platform messages may fail, so we use a try/catch PlatformException.
// We also handle the message potentially returning null.
try {
platformVersion = await MyPlugin.platformVersion ?? false;
} on PlatformException {
debugPrint('Failed to get platform version.');
}
// If the widget was removed from the tree while the asynchronous platform
// message was in flight, we want to discard the reply rather than calling
// setState to update our non-existent appearance.
if (!mounted) return;
setState(() {
_platformVersion = platformVersion ?? false;
});
}
[@override](/user/override)
Widget build(BuildContext context) {
return MaterialApp(
home: Scaffold(
appBar: AppBar(
title: const Text('设备类型检测插件示例应用'),
),
body: Center(
child: Text('运行于: $_platformVersion\n'),
),
),
);
}
}

catch_device_type
是一个用于检测设备类型的 Flutter 插件。它可以帮助你识别当前运行的设备是手机、平板、台式机还是其他类型的设备。以下是如何使用 catch_device_type
插件的步骤:
1. 添加依赖
首先,你需要在 pubspec.yaml
文件中添加 catch_device_type
插件的依赖。
dependencies:
flutter:
sdk: flutter
catch_device_type: ^1.0.0 # 请检查最新版本
然后运行 flutter pub get
来获取依赖。
2. 导入插件
在你的 Dart 文件中导入 catch_device_type
插件:
import 'package:catch_device_type/catch_device_type.dart';
3. 使用插件
你可以使用 CatchDeviceType
类中的方法来检测设备类型。以下是一些常用的方法:
void checkDeviceType() async {
String deviceType = await CatchDeviceType.deviceType;
switch (deviceType) {
case 'phone':
print('This is a phone.');
break;
case 'tablet':
print('This is a tablet.');
break;
case 'desktop':
print('This is a desktop.');
break;
default:
print('Unknown device type.');
}
}
4. 完整示例
以下是一个完整的示例,展示了如何在 Flutter 应用中使用 catch_device_type
插件:
import 'package:flutter/material.dart';
import 'package:catch_device_type/catch_device_type.dart';
void main() {
runApp(MyApp());
}
class MyApp extends StatelessWidget {
[@override](/user/override)
Widget build(BuildContext context) {
return MaterialApp(
home: DeviceTypeChecker(),
);
}
}
class DeviceTypeChecker extends StatefulWidget {
[@override](/user/override)
_DeviceTypeCheckerState createState() => _DeviceTypeCheckerState();
}
class _DeviceTypeCheckerState extends State<DeviceTypeChecker> {
String _deviceType = 'Unknown';
[@override](/user/override)
void initState() {
super.initState();
checkDeviceType();
}
void checkDeviceType() async {
String deviceType = await CatchDeviceType.deviceType;
setState(() {
_deviceType = deviceType;
});
}
[@override](/user/override)
Widget build(BuildContext context) {
return Scaffold(
appBar: AppBar(
title: Text('Device Type Checker'),
),
body: Center(
child: Text('Device Type: $_deviceType'),
),
);
}
}
