[英]Container widget overflows other widgets- Flutter
This is the expected screen and the container will collapse and expand based on the text displayed and should only occupy the space left out by placing other icons.这是预期的屏幕,容器将根据显示的文本折叠和展开,并且应该只占用放置其他图标留下的空间。
But see the flutter implemented screen.但请参阅 flutter 实现的屏幕。 The icons are moved to the right on container expansion and shows overflowed pixel error.
图标在容器扩展时向右移动,并显示溢出像素错误。
