Text is not painted to the Canvas at the correct position on Flutter 3.0.0

[bdlukaa]

Steps to Reproduce

Execute flutter run on the package example app with two different flutter versions:

1. Flutter 2.10.0
2. Flutter 3.0.0

Expected results:

Actual results:

For some reason, the text is not painted (painting operation occurs here) at the same position on these two different versions. To paint the background, I use the LineMetrics generated by TextPainter.generateLineMetrics positions. They are the same for both versions (you can run the tests and see), so something may be wrong on paiting the text into the Canvas.
