How to disconnect from all devices?

[atauf]

I'm currently connecting to devices in a for loop, but when I try to disconnect using a for loop, I can only seem to get one device to disconnect.

Thinking that it had something to do with the for loop, I decided to make a button that disconnects from one devices at a time. Again, it works for the first one, and then doesn't work again after that.

@remonh87 I'd really appreciate any input you might have.

Example of connecting code:

for (String deviceId in listOfDeviceIds) async {
  try{
    await connectAndLoad(deviceId: deviceId, interactor: interactor, index: index);
  } catch (e) {
    print(e);
  }
}
Future<void> connectAndLoad(
      {required String deviceId,
      required BleDeviceInteractor interactor,
      required int index}) async {
    _logMessage('Start connecting to $deviceId');
    print('Start connecting to $deviceId');
    _connection = _ble.connectToDevice(id: deviceId).listen((update) async {
      _logMessage(
          'ConnectionState for device $deviceId : ${update.connectionState}');
      _deviceConnectionController.add(update);

      if (update.connectionState == DeviceConnectionState.connected) {
        await loadParameters(
            connectionStatus: update, interactor: interactor, index: index);
      }
    }, onError: (e) {
      print('Connecting to device $deviceId resulted in error $e');
      _logMessage('Connecting to device $deviceId resulted in error $e');
    }, onDone: () {
      print(
          "CONNECT AND LOAD FUNCTION IS DONE ---------------------------------");
    });
  }

Example of disconnect code:

// inside of widget, but outside of build function
int _deviceIndex = 0;

ElevatedButton(
                  onPressed: () async {
                    List deviceIdList = _deviceIdList;
                    
                    // ------------ This for loop didn't work (only disconnects one device) -----------------------

                    // for (String deviceId in deviceIdList) {
                    //   await Provider.of<BleDeviceConnector>(context,
                    //           listen: false)
                    //       .disconnect(deviceId);


                    // attempt at disconnect from one device each time I press the button (I'm aware of index out of range error that 
                    // will happen, but it should work until then

                    await Provider.of<BleDeviceConnector>(context,
                            listen: false)
                        .disconnect(deviceIdList[_deviceIndex])
                        .then((value) => _deviceIndex++);
                    print("_deviceIndex: $_deviceIndex");
                    // }
                  },
                  child: Text("Disconnect from all Selected Devices")),
