EdgeInsetsGeometry Class EdgeInsets Class 在 Flutter Z35900D987289A83AF1011D18A9FZ7C3 之间的区别
[英]Difference between EdgeInsetsGeometry Class EdgeInsets Class in Flutter Dart?
问题描述
I'm trying to understand some basic elements of Flutter.
我试图了解 Flutter 的一些基本元素。 When I try to use the property of a container, like padding, I believe that it expects an "EdgeInsetGeometry" class.当我尝试使用容器的属性（如填充）时，我相信它需要一个“EdgeInsetGeometry”class。 When I read the document about this class, I see that there is "EdgeInset" class as an implementer.当我阅读有关此 class 的文档时，我看到有“EdgeInset”class 作为实现者。 I'm confused about this point since I don't know which one I should use.我对这一点感到困惑，因为我不知道应该使用哪一个。
The document for Flutter is kind of confusing for me at the moment. Flutter 的文档目前对我来说有点混乱。 Could you please help to explain the difference between these two, and how I can figure out what the type of the output is for a class using flutter document?您能否帮助解释这两者之间的区别，以及如何使用 flutter 文档确定 output 的类型对于 class 是什么？
