flutter插件 - device_info（获取设备信息）

简介

官方文档

在应用内部获取当前设备信息。

Flutter是全平台框架，可以在多种平台上运行，获取设备信息之前要先判断程序运行在哪种平台。
通过dart.io包下的Platform类来获取

class Platform {
  // ...
  static final bool isLinux = (_operatingSystem == "linux");
  static final bool isMacOS = (_operatingSystem == "macos");
  static final bool isWindows = (_operatingSystem == "windows");
  static final bool isAndroid = (_operatingSystem == "android");
  static final bool isIOS = (_operatingSystem == "ios");
  static final bool isFuchsia = (_operatingSystem == "fuchsia");
  // ...
}

使用

• 修改pubspec.yaml文件，添加依赖device_info

# ...
dev_dependencies:
  # ...
  device_info: ^0.4.2+8
# ...

• 在代码中使用

import 'dart:io';
import 'package:device_info/device_info.dart';

void getDeviceInfo() async {
  DeviceInfoPlugin deviceInfo = DeviceInfoPlugin();
  if (Platform.isIOS) {
    IosDeviceInfo iosDeviceInfo = await deviceInfo.iosInfo;
  } else if (Platform.isAndroid) {
    AndroidDeviceInfo androidDeviceInfo = await deviceInfo.androidInfo;
  }
}

• IosDeviceInfo类

class IosDeviceInfo {
  // ...
  final String name;
  final String systemName;
  final String systemVersion;
  final String model;
  final String localizedModel;
  final String identifierForVendor;
  final bool isPhysicalDevice;
  final IosUtsname utsname;
  // ...
}

• AndroidDeviceInfo类

class AndroidDeviceInfo {
  // ...
  final AndroidBuildVersion version;
  final String board;
  final String bootloader;
  final String brand;
  final String device;
  final String display;
  final String fingerprint;
  final String hardware;
  final String host;
  final String id;
  final String manufacturer;
  final String model;
  final String product;
  final List<String> supported32BitAbis;
  final List<String> supported64BitAbis;
  final List<String> supportedAbis;
  final String tags;
  final String type;
  final bool isPhysicalDevice;
  final String androidId;
  // ...
}
