Features

To Start Dfu Pic a file by using any File Picker Plugin and convert File to buffer pass that buffer to this method and start DFU

Note: startDfu will open dialog to choose for a Device if , that device is already in Dfu mode , then it will start transfeing firmware else ,first device will be booted to Dfu and onDfuModeAvailable callback will be called , here ask user to scan for device again by using any dialog or someting

  NordicDfuWeb nordicDfuWeb = NordicDfuWeb();


  startDfu() async {
    FilePickerResult? result = await FilePicker.platform.pickFiles();
    if (result != null) {
      PlatformFile file = result.files.first;
      await nordicDfuWeb.startDfu(
          uint8list: file.bytes!,
          onProgress: (data) {
            print(data);
          },
          onComplete: (data) {
            print(data);
          },
          onError: (err) {
           print(err);
          },
          onLogs: (data) {
            print(data);
          },
          onDfuModeAvailable: (package) {
              ///Show Dialog to The User to choose Dfu Device Again
            Get.defaultDialog(
                title: '',
