edgeWidth default value not listed in Docs or Typings

Current Behavior

• edgeWidth is listed in docs with no default value

Expected Behavior

• edgeWidth lists what its default value is in the typings or in the docs

Hello, I apologize if creating an issue for this is not the appropriate action. However while implementing the drawer navigation I realized it was sort of hard to swipe. Luckily you have provided the ability to change that with edgeWidth.. unfortunately I can't seem to determine the "default" value as I am trying to gauge how much I want to increase it.

Thank you!

首先检查 drawer navigation 文档和类型定义中关于 edgeWidth 选项的内容。根据现有实现确认默认值，然后在文档或类型定义中记录该值，以便用户确定需要将其增加多少。
