How to reproduce:

  1. Launch the example app. (I used a TV 6.0 emulator.)
  2. Enter some text in the text field and click PLAY, and then click STOP or PAUSE while the audio is playing.
  3. Click PLAY again and see this error message:
I/ConsoleMessage(11739): flutter: Playing
I/ConsoleMessage(11739): flutter: Cancel
E/ConsoleMessage(11739): [ERROR:flutter/lib/ui/ui_dart_state.cc(186)] Unhandled Exception: PlatformException(Invalid Operation, Invalid Operation, null, null)

Which binary did you test with? I couldn't reproduced on mobile emulator.
When it comes TV profile, as mentioned in the PR, I couldn't check on the emulator. But when I checked it on the real target, I couldn't reproduce it. Test binary I tested is as follows.

Model=Tizen6/TV;
Build=latest;
Release=latest;
[Build]
Type=eng;
Date=20201111_193150;
Time=19:31:50;
Variant=NONE;

It may be a binary issue or a platform issue.

@rookiejava I tested on various devices (R800/TM1/TV emulator) and they all have the same issue. Here is the full log:

Maybe the m_speaking value is not being updated properly when stop or pause is received.

Ok. I'll check again. But tell me exactly what binary you tested.

Ah, you're saying that the app doesn't terminated abnormally, but there's an error. Anyway, let me check again.

The important part is the second step. I clicked the STOP (PAUSE) button before speaking ended.
