From version 5.0.0, the callbacks are defined as function parameters in NordicDfu().startDfu(). Please see the example app for more information.

Fork from flutter_nordic_dfu and updated with latest dependencies.

This library allows you to do a Device Firmware Update (DFU) of your nrf51 or nrf52 chip from Nordic Semiconductor. It works for Android and iOS.

This is the implementation of the reference "react-native-nordic-dfu"

For more info about the DFU process, see: Resources

1. Add your dfu zip file to example/assets/file.zip

2. Run example project

3. Scan device

4. Start dfu

You can pass an absolute file path or asset file to NordicDfu

await NordicDfu().startDfu(
            'EB:75:AD:E3:CA:CF', '/file/to/zip/path/file.zip'
         );
// With callback
await NordicDfu().startDfu(
      'EB:75:AD:E3:CA:CF',
      'assets/file.zip',
      fileInAsset: true,
      onProgressChanged: (
        deviceAddress,
        percent,
        speed,
        avgSpeed,
        currentPart,
        partsTotal,
      ) {
        print('deviceAddress: $deviceAddress, percent: $percent');
      },
    );

/// just set [fileInAsset] true
await NordicDfu().startDfu(
            'EB:75:AD:E3:CA:CF', 'assets/file.zip',
            fileInAsset: true,
         );
