Currently you need to send the data in string format (Serializing the response before sending to the client).

[phamhuudat]

I can only handle this client side problem. Do you have a way to handle it in the signalr plugin code or in my app?
thankyou

[AyonAB]

You probably can. You need to fork the repo, change the native code related to receiving data from server for both android & iOS.

It's probably late. But here is the forked repo that can resolve the issue: signalr_flutter

just add this line to your pubspec.yaml and delete all duplicate packages error.

dev_dependencies:
  signalr_flutter:
    git:
      url: https://github.com/usa-12/signalr_flutter

then run flutter clean and flutter pub get.

@AyonAB please fix this. Because in multiple cases we don't just send plain text. And the fixed code is up there. Maybe it could lead to other problems but for now it works fine

I'm open for any contribution here. Currently I'm too busy to maintain it properly.
