Dart snapshot generator failed with exit code -9

Question

Debugging mode working well but when I tried to run it as release mode or building apk it's not working. Tried all things that I could but it's not working (Create a new project shift it). Other projects working well.

I have solved the problem. It was my mistake in code. I have a that I convert SVG to flutter Custompainter FlutterShapeMaker. This was more than 3Klines long and for some reason, it was stopping the build. After removing everything I was able to build the app for release.
