Does not work in profile mode

[sujanbhattaraiofficial]

In my case it looks fine in debug mode but when I run the app as profile mode it throws an exception

E/flutter ( 4423): [ERROR:flutter/lib/ui/ui_dart_state.cc(157)] Unhandled Exception: Failed

I think its because of the "boundary.debugNeedsPaint" boolean in "_captureImage" function. If you look at docs, it says it should only be used for tests and asserts since it is only set in debug mode.

So simply comment out the boolen, and it should work fine.

void _captureImage(Duration timeStamp) async {
    final pixelRatio = MediaQuery.of(context).devicePixelRatio;
 final boundary =
        _boundaryKey.currentContext.findRenderObject() as RenderRepaintBoundary;
    // if (boundary.debugNeedsPaint) {
    //   await Future.delayed(const Duration(milliseconds: 20));
    //   return _captureImage(timeStamp);
    // }
    final image = await boundary.toImage(pixelRatio: pixelRatio);
    setState(() => _image = image);
  }
