flutter pub add flutter_blue_classic根據套件公開資料產生的選型評估，僅供參考。
flutter_blue_classic 是一個 Flutter 插件，可在 Android 上實現與藍牙經典設備的通訊。它提供了一個簡單的 API，用於發現、連接並交換資料給經典藍牙周邊裝置。專為需要與舊式藍牙硬體（如音訊裝置、感測器或自訂物聯網裝置）互動的應用程式而設計，可無縫整合到 Flutter 應用中。該插件支援掃描、配對以及處理已連接裝置的資料串流等基本藍牙作業。由 lenhart.dev 維護，並託管在 GitHub 上，以確保透明度和社群貢獻。

Flutter_blue_classic is a flutter plugin for communicating with bluetooth classic devices. If you want to use an Bluetooth low energy (BLE) device, you might want to consider flutter_blue_plus.
This plugin is currently only compatible with Android. iOS does not provide a similar interface for Bluetooth Classic like Android does. On iOS your BL device must be MFi (Made for iPod/iPhone) certified and you will have to use the External Accessory Framework. Since this is out of the scope of this package, you will have to implement this yourself.
This package is only compatible with Android SDK 21 or higher. Please set your minSdkVersion in the android/app/build.gradle accordingly.
As the Android permission requirements can differ from case to case, this package does not define any permissions in it's Manifest. It is therefore necessary to declare them yourself. For detailed information, take a look at the Android Developer Documentation on Permissions.
Below are two common presets:
In the android/app/src/main/AndroidManifest.xml add:
<!-- Permissions for Android 12 or above -->
<uses-permission android:name="android.permission.BLUETOOTH_SCAN" android:usesPermissionFlags="neverForLocation" />
<uses-permission android:name="android.permission.BLUETOOTH_CONNECT" />
<!-- legacy for Android 11 or lower -->
<uses-permission android:name="android.permission.BLUETOOTH" android:maxSdkVersion="30" />
<uses-permission android:name="android.permission.BLUETOOTH_ADMIN" android:maxSdkVersion="30" />
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" android:maxSdkVersion="30" />
<!-- legacy for Android 9 or lower -->
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" android:maxSdkVersion="28" />
In the android/app/src/main/AndroidManifest.xml add:
<!-- Permissions for Android 12 or above -->
<uses-permission android:name="android.permission.BLUETOOTH_SCAN" />
<uses-permission android:name="android.permission.BLUETOOTH_CONNECT" />
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
<!-- legacy for Android 11 or lower -->
<uses-permission android:name="android.permission.BLUETOOTH" android:maxSdkVersion="30" />
<uses-permission android:name="android.permission.BLUETOOTH_ADMIN" android:maxSdkVersion="30" />
<!-- legacy for Android 9 or lower -->
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" android:maxSdkVersion="28" />
Then pass the accessFineLocation parameter when initializing the plugin:
final blueClassic = FlutterBlueClassic(usesFineLocation: true);
| Description | |
|---|---|
| isSupported | Checks whether the device supports Bluetooth |
| isEnabled | Checks whether Bluetooth is enabled |
| adapterStateNow | Current state of the bluetooth adapter |
| adapterState | Stream of on, off and intermediary states of the bluetooth adapter |
| bondedDevices | Returns the list of bonded (paired) devices |
| startScan | Starts a scan for Bluetooth devices |
| stopScan | Stop an existing scan for Bluetooth devices |
| isScanningNow | Checks whether the Bluetooth adapter is currently scanning. |
| isScanning | Stream whether the device is scanning for BL devices. |
| scanResults | Stream of found devices during scan |
| turnOn | Requests to turn the bluetooth adapter on |
| bondDevice | Requests to create a bond with a bluetooth device |
| connect | Tries to connect with a bluetooth device |
| Description | |
|---|---|
| input | The stream of data received from the connected BL device |
| output | A stream sink to send byte data to the connected BL device |
| writeString | A helper to send utf-8 encoded strings to the remote device |
| isConnected | Indicates whether the connection is still open. |
| dispose | This should be called, when the Connection is no longer needed and will call finish (see below). |
| finish | This will wait for any ongoing writes to be finished and gracefully close the connection. |
| close | This will immediately close the connection. |
flutter_blue_classic is loosely based on flutter_bluetooth_serial.
