Make sure the device is advertising which service UUID’s it supports. Troubleshooting Scanning for service UUID’s doesn’t return any results But it will just happen to collide with the UUID of a wireless camera - and you will have a really weird, hard to track down problem only effecting one user. Stream of characteristic’s value when changed. However, if they do happen, it will be a really weird and hard to reproduce bug (for example a user will setup a fitness application with the UUID of the heart rate monitor. Sets notifications or indications on the characteristic. Retrieves the value of the characteristic. Request to change the MTU for the device.

Stream of state changes for the Bluetooth Device. Requires that discoverServices() has completed. Stream of state changes for the Bluetooth Adapter.Ĭhecks whether the device supports Bluetooth.Ĭhecks if Bluetooth functionality is turned on.Ĭancels an active or pending connection to the device.ĭiscovers services offered by the remote device as well as their characteristics and descriptors. Starts a scan for Bluetooth Low Energy devices. Note that iOS will not allow that you request the MTU size, but will always try to negotiate the highest possible MTU (iOS supports up to MTU size 185) Reference FlutterBlue API Var subscription = ((scanResult) ) Read the MTU and request larger size final mtu = await Usage Obtain an instance FlutterBlue flutterBlue = FlutterBlue.instance Scan for devices // Start scanningįlutterBlue.startScan(timeout: Duration(seconds: 4)) The BluetoothDevice object is then used to directly interact with characteristics and descriptors. Once connected to a device, the BluetoothDevice object can discover services ( BluetoothService), characteristics ( BluetoothCharacteristic), and descriptors ( BluetoothDescriptor). Using the FlutterBlue instance, you can scan for and connect to nearby devices ( BluetoothDevice). Without any further ado, lets dive into the code. Cross-Platform Bluetooth LEįlutterBlue aims to offer the most from both platforms (iOS and Android). This post shows you a simpe approache to generate a random number string in Dart (and Flutter as well). Having trouble adapting to the latest API? I’d love to hear your use-case, please contact me. Please be fully prepared to deal with breaking changes. Otherwise, either use *.name only or androidDeviceInfo.id alongside with *.name.This library is actively developed alongside production apps, and the API will evolve as we continue our way to version 1.0.

You can probably get away with using only androidDeviceInfo.name as it would not change ever.ĪndroidDeviceInfo.id can also change if OS is updated as it is an android os version.ĪndroidDeviceInfo.androidId should only be used if device uses fix mac address as mentioned in point 1. You can confirm this by yourself by changing androidDeviceInfo.id to androidDeviceInfo.androidId above. This would cause the androidId to change when switiching networks. This feature is enabled by default unless disabled manually. Mobile devices above Android OS 10/11 will generate a randomized MAC. Follow the instructions from Flutter16049 to resolve the issue (Cocoapods 1.5+ is mandatory). There is a known issue for integrating swift plugin into Flutter project using the Objective-C template. Note: The plugin is written in Swift for iOS. This would change when your mac address changes. Add to pubspec.yaml: dependencies: beacons: 0.3.0. Usage: String deviceId = await getUniqueDeviceId() ĭo not use androidDeviceInfo.androidId. App Lifecycle Observer (App in foreground, background and terminated) Transform. TabBar (11 pcs) Portrait and Landscape mode. Print('Running on $' // unique ID on Android Row and Column (align, space between and around, row and column combination) SnackBar (color, time, multiline, with icon, floating, up screen) ListView and GridView.

How to use: import 'package:device_info_plus/device_info_plus.dart' The plugin device_info has given deprecation notice and replaced by LinuxDeviceInfo linuxInfo = await deviceInfo.linuxInfo WebBrowserInfo webInfo = await deviceInfo.webBrowserInfo ĭeviceIdentifier = webInfo.vendor + erAgent + () The web doesnt have a device UID, so use a combination fingerprint as an example IosDeviceInfo iosInfo = await deviceInfo.iosInfo ĭeviceIdentifier = iosInfo.identifierForVendor Import 'package:device_info_plus/device_info_plus.dart' ĭeviceInfoPlugin deviceInfo = DeviceInfoPlugin() ĪndroidDeviceInfo androidInfo = await deviceInfo.androidInfo ĭeviceIdentifier = androidInfo.androidId Here is an example usage: import 'package:flutter/foundation.dart' show kIsWeb It supports more platforms than device_info and aims to support all that are supported by flutter.

Update : The recommended way is now the extended community plugin called device_info_plus.
