Q3:If you are running the flutter app, the [mark] of [chart] can be displayed normally, but the [mark] cannot be displayed normally after being integrated into Android, you may need to make the following changes: Source file: line 197 of core/utils/screen_utils.dart, the variable [_screenDensity] is changed to [_screenWidth] (如果你在运行flutter app时，[chart]的[mark]能正常显示，但是集成到Android后却无法正常显示[mark],可能要做如下修改： 源文件：core/utils/screen_utils.dart的第197行，的变量[_screenDensity]改为[_screenWidth])
