How to get Device Information in Flutter
Last updated Nov 02, 2021As you know Flutter is an open-source UI software development kit created by Google. It is used to develop cross-platform applications for Android, iOS, Linux, Mac, Windows,
So you can also get device information as well for platforms like Android, iOS, Linus, Mac, Windows in this tutorial we will see how you can show device info in Flutter Let's Start
Step 1: Create a new Flutter Application.
Step 2: Add a line like this to your package's pubspec.yaml.
|
Step 3: Now you can use a plugin called DeviceInfoPlugin in your application so, add a function in your initState that will check the Platform which you are using for example
-
Platform.isAndroid
-
Platform.isIOS
-
Platform.isLinux
-
Platform.isMacOS
-
Platform.isWindows
with this when you run the app it will detect the Platform that you are using.
Step 4: Now you can get your information by writing build(dot) information that you want to get
for example
|
build.brand, build.device, build.manufacture, build.model etc. |
This will get you the information in String form which you can use to display in your app. So, we can create a function that will show all the information with that platform
for example function for android application:
|
Map _readAndroidBuildData(AndroidDeviceInfo build) { return { 'version.securityPatch': build.version.securityPatch, 'version.sdkInt': build.version.sdkInt, 'version.release': build.version.release, 'version.previewSdkInt': build.version.previewSdkInt, 'version.incremental': build.version.incremental, 'version.codename': build.version.codename, 'version.baseOS': build.version.baseOS, 'board': build.board, 'bootloader': build.bootloader, 'brand': build.brand, 'device': build.device, 'display': build.display, 'fingerprint': build.fingerprint, 'hardware': build.hardware, 'host': build.host, 'id': build.id, 'manufacturer': build.manufacturer, 'model': build.model, 'product': build.product, 'supported32BitAbis': build.supported32BitAbis, 'supported64BitAbis': build.supported64BitAbis, 'supportedAbis': build.supportedAbis, 'tags': build.tags, 'type': build.type, 'isPhysicalDevice': build.isPhysicalDevice, 'androidId': build.androidId, 'systemFeatures': build.systemFeatures, }; } |
Step 5: So we can use this function in your ListView in your Application to Display Device Information.
|
body: ListView( children: _deviceData.keys.map( (String property) { return Row( children: [ Container( padding: const EdgeInsets.all(10.0), child: Text( property, style: const TextStyle( fontWeight: FontWeight.bold, ), ), ), Expanded( child: Container( padding: const EdgeInsets.fromLTRB(0.0, 10.0, 0.0, 10.0), child: Text( '${_deviceData[property]}', maxLines: 10, overflow: TextOverflow.ellipsis, ), )), ], ); }, ).toList(), ), |
