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!

まず、edgeWidth オプションについて、drawer navigation のドキュメントと型定義を確認します。既存の実装からデフォルト値を確認し、その値をドキュメントまたは型定義に記載して、ユーザーがどの程度増やす必要があるか判断できるようにします。
