Getting Error: This ticker was canceled

[KimAloy]

Hi, I'm also getting the error when I use the HeartBeat on the second page and press the back button.
E/flutter ( 3021): [ERROR:flutter/shell/common/shell.cc(93)] Dart Unhandled Exception: This ticker was canceled: Ticker(created by _HeartBeatState#56128)

@rohitsangwan01 @KimAloy sorry for getting back to you later on this ... let me fix this and get back to your ASAP

@imujtaba8488 @rohitsangwan01 The error seems to be thrown by _controller.repeat().orCancel;

I replaced it with code below and it doesn't throw any errors

@override
  void didUpdateWidget(ABeats oldWidget) {
    _controller.reset();
    // _controller.repeat().orCancel;          <---- replaced this with code below
    _controller.forward();
    _controller.repeat();
    super.didUpdateWidget(oldWidget);
  }

and this

  // Since a heartbeat, so repeats infinitely.
    // _controller.repeat().orCancel;      <---- replaced this with code below
    _controller.forward();
    _controller.repeat();

same error

Click to open the method you want to use (Ctrl+Click in android studio).

Replace every _controller.repeat().orCancel; with these two lines of code:
_controller.forward(); _controller.repeat();

I implemented that, but i still get the same error on the HeartBeat animation sometimes (that's why i closed my pull request)
