在移动应用开发中，获取设备信息是常见的需求。无论是用于用户行为分析、设备适配优化，还是数据埋点统计，Flutter社区推出的神器device_info_plus都能轻松实现跨平台设备信息获取。本文将通过代码示例和实战数据，带你掌握它的核心用法！
一、快速集成步骤
1. 添加依赖
在 pubspec.yaml 中引入插件：
dependencies:
device_info_plus: ^9.0.0
2. 核心代码实现
Future<void> initPlatformState() async {
var deviceData = <String, dynamic>{};
if (Platform.isIOS) {
deviceData = _readIosDeviceInfo(await deviceInfoPlugin.iosInfo);
}
if (Platform.isAndroid) {
deviceData = _readAndroidBuildData(await deviceInfoPlugin.androidInfo);
}
setState(() {
_deviceData = deviceData;
});
}
Map<String, dynamic> _readAndroidBuildData(AndroidDeviceInfo build) {
return <String, dynamic>{
'version.securityPatch': build.version.securityPatch,
'version.sdkInt': build.version.sdkInt,
'version.release': build.version.release,

'physicalRamSize': build.physicalRamSize,
'availableRamSize': build.availableRamSize,
};
}
Map<String, dynamic> _readIosDeviceInfo(IosDeviceInfo data) {
return <String, dynamic>{
'name': data.name,
'systemName': data.systemName,
'systemVersion': data.systemVersion,
'model': data.model,
'modelName': data.modelName,
'localizedModel': data.localizedModel,
'identifierForVendor': data.identifierForVendor,
'isPhysicalDevice': data.isPhysicalDevice,
'isiOSAppOnMac': data.isiOSAppOnMac,

};
}
