Flutter Material App error on debug when switching scene - flutter

Question

I was making 2 scene with google Maps and drawing polyline on the map, the apps have no problem running and everything working fine, however on the debug there is this big stack of error in debug which I have no idea what it meant, can anyone tell me what is this ? It is kind of concerning for me
Below is the error on the debug,
════════ Exception caught by rendering library ═════════════════════════════════
Failed to rasterize a picture: unable to create render target at specified size.
The callstack when the image was created was:

The relevant error-causing widget was
MaterialApp
Edit:
Here's the packages and code of the scene that triggered the error in the debug, for extra information, the error did not triggered consistently. I have no idea what trigered it, the materialapp exist on the home page. I use navigator function to switch scene
