This is my code.

void startListeningToScannedResults() async {
    // Check platform support and necessary requirements
    final can = await WiFiScan.instance.canGetScannedResults(askPermissions: true);
    switch (can) {
      case CanGetScannedResults.yes:
      // Check if the subscription is null before creating a new one
        if (subscription == null) {
          subscription = WiFiScan.instance.onScannedResultsAvailable.listen((results) {
            accessPoints = results;
            uniqueWifiList.value = <dynamic>{...accessPoints.map((WiFiAccessPoint) => WiFiAccessPoint.ssid)}.where((ssid) => ssid != null).cast<String>().toList();
            if (selectedWifiName.value == '') {
              selectedWifiName.value = uniqueWifiList[0];
            }
          });
        }
        break;
    // Handle other cases as needed
    }
  }
  void scanBleDevices() async {
    final prefix = deviceNamecontroller.text;
    print("PREFIX : $prefix");

    if (isSetupButtonPressed.value) {
      print("Scan operation already in progress");
      return;
    }

    try {
      isSetupButtonPressed.value = true;

      final scannedDevices = await _flutterEspBleProvPlugin.scanBleDevices(prefix);

      bleDevicesList.value = scannedDevices;

      if (selectedDeviceName.value.isEmpty && bleDevicesList.isNotEmpty) {
        selectedDeviceName.value = bleDevicesList.first;
      }
    } catch (error) {
      // Handle any errors that occur during BLE scanning
      print("Error during BLE scanning: $error");
      Get.snackbar(
        "Error",
        "Failed to scan BLE devices: $error",
        snackPosition: SnackPosition.BOTTOM,
      );
    } finally {
      // Reset the flag indicating that the scan operation is complete
      isSetupButtonPressed.value = false;
    }
  }

I am integrating ESP Ble Provisioning I just want to get user permission and then it should work properly
