A1:change ‘../lib/mp/chart/chart.dart:51’
before：
ImageGallerySaver.saveImage(Uint8List.fromList(imgFile.readAsBytesSync())) .then((value) { imgFile.delete(); });
after：
var result = ImageGallerySaver.saveImage(Uint8List.fromList(imgFile.readAsBytesSync())); if(result is Future<dynamic>){ result.then((value) => imgFile.delete()); }

Q2:`../lib/mp/core/utils/painter_utils.dart:15:34: Error: The getter 'text' isn't defined for the class 'InlineSpan'.

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])
