Flutter信息获取插件info_pl的潜在功能使用

平台支持

使用

要使用此插件，在您的 pubspec.yaml 文件中添加 info_pl 作为依赖项。

dependencies:
  info_pl: ^版本号

示例

首先，导入 package:info_pl/info_pl.dart 并初始化 InfoPl。

import 'package:flutter/material.dart';
import 'dart:async';

import 'package:info_pl/info_pl.dart';

static final InfoPl _infoPl = InfoPl();

void main() => runApp(
      const MaterialApp(
        home: Material(
          child: Center(
            child: ElevatedButton(
              onPressed: _getDeviceInfo,
              child: Text('Get Device Info'),
            ),
          ),
        ),
      ),
    );

Future<void> _getDeviceInfo() async {
  if (!await _infoPl.init()) {
    throw Exception('Could not to get device info');
  }
}

信息文本生成器示例

此插件提供了一个方法，可以以通用方式获取平台特定的设备信息。通过该方法获取的数据可以以有组织且可读的方式可视化。

import 'package:flutter/material.dart';
import 'dart:async';

import 'package:info_pl/info_pl.dart';

static final InfoPl _infoPl = InfoPl();
DeviceInfo? _deviceInfo;
String? _deviceInfoText;

void main() {
  _getDeviceInfo();
  runApp(
    const MaterialApp(
      home: Material(
        child: SingleChildScrollView(
          child: Text(
            _deviceInfoText ?? 'Loading...',
          ),
        ),
      ),
    ),
  );
}

Future<void> _getDeviceInfo() async {
  String? deviceInfoText;
  
  try {
    _deviceInfo = await _infoPl.init();
    deviceInfoText = _deviceInfo.toString();
  } on PlatformException {
    deviceInfoText = 'Failed to get device info.';
  }

  setState(() {
    _deviceInfoText = deviceInfoText!;
  });
}

通过DeviceInfo类单独访问数据示例

此外，还可以通过 DeviceInfo 类单独访问获取到的数据。

import 'package:info_pl/info_pl.dart';

static final InfoPl _infoPl = InfoPl();
DeviceInfo? _deviceInfo;

Future<void> _getDeviceInfo() async {
  String? deviceBrandAndModel;
  
  try {
    _deviceInfo = await _infoPl.init();
    deviceBrandAndModel = '${_deviceInfo!.brand} ${_deviceInfo!.model}';
  } on PlatformException {
    deviceBrandAndModel = 'Failed to get device info.';
  }
}

生成UUID示例

使用 ID、android_ID 和 board 数据创建一个独特的 UUID。此生成的 UUID 可以像其他通过 DeviceInfo 类获取的数据一样访问。

import 'package:info_pl/info_pl.dart';

static final InfoPl _infoPl = InfoPl();
DeviceInfo? _deviceInfo = await _infoPl.init();
String? uuId = _deviceInfo!.uuId;
