java.io.FileNotFoundException in example app about flutter-nordic-dfu HOT 6 CLOSED

Current, you should pass a absolute path to FlutterNordicDfu.startDfu like /data/local/tmp/file.zip.

In plugin, it use File(path) to open it

from flutter-nordic-dfu.

@fengqiangboy Absolute path from the root of the app?
Should It be updated in the pubspec.yaml as well?
Example would be much appreciated 😄

As you have used assets/file.zip in your example itself

from flutter-nordic-dfu.

In early version, I use assets/file.zip to test, because at the time I use a tool to get Asset file in native code, but it would import third dependent, so I remove it now.

I will consider how to achieve better implementation that can get flutter assets file path in native code.

from flutter-nordic-dfu.

Oh, which plugin did you use earlier? can you also give me an estimate on how long will you take to implement your version of the same?

I'll keep this issue open until then.

from flutter-nordic-dfu.

Use com.blankj:utilcode,

the code look like:

// assets file from flutter
filePath = "assets/file.zip"

filePath = registrar.lookupKeyForAsset(filePath)

val tempFileName = PathUtils.getExternalAppCachePath() + UUID.randomUUID().toString()

// copy asset file to temp path
ResourceUtils.copyFileFromAssets(filePath, tempFileName)

// now, the path is an absolute path, and can pass it to nordic dfu libarary
filePath = tempFileName

from flutter-nordic-dfu.

Current, it can support asset file in flutter, you can try it in version 2.0.0

await FlutterNordicDfu.startDfu(
            'EB:75:AD:E3:CA:CF', 'assets/file.zip',
            progressListener: ProgressListenerListener(),

/// asset file should add this parameter
            fileInAsset: true,
         );
