4 years ago @iapicca hi It can run on the device, which is the error report of this code.
... Directory dir = await getApplicationDocumentsDirectory(); String dirpath=dir.path; File file = new File('$dirpath/$id.pdf'); await Http().download("/thsoft-sm-website/inspection/record/mShowPDF/$id","$dirpath/$id.pdf"); var data = await DefaultAssetBundle.of(context).load('$dirpath/$id.pdf'); var byte = data.buffer.asUint8List(); file =await file.writeAsBytes(byte); return file;
Unable to load asset: /data/user/0/com.thsoft.flutter_app2/app_flutter/1.pdf but When I reload, it will run normally and no error will be reported.

4 years ago Hi again @suowangjing
the error you are reporting can have several causes
that might or might not be related to Flutter.
flutter run --verbose can help to understand the situation,
unfortunately the log you provided wasn't not very useful
since exited immediately due to a lack of available devices.
Could you please try again
Also, to better address the issue, would be helpful if you could post a self contained app on github or the steps to reproduce it. Thank you

4 years ago @iapicca hi ,I hope you can look at this problem again！！！ It's not this error. This interface is not the cause of that error. It's the login page. The error code is another page. I got the data from HTTP and downloaded it to the cache. But I can't load the asset. But after I reload, it's normal. I feel that the method defaultassetbundle. Of (context). Load() of fluent doesn't come from the latest resources. Load from the latest resource after I reload。

So it's not the problem of HTTP requests. The first time the request arrives, it's put in the cache. It can't be read. It can only be read after reload.

4 years ago When I used to use flutter 1.3.2, there was no problem with this code. I upgraded it to 1.10.14 before this problem occurred.
