Drag behavior is inconsistent with the common behavior

[Jackjun724]

I tried the dragging of ModalSheet in iOS and YouTube, and they share a common characteristic: even if I drag a very short distance, as long as the dragging speed is fast enough, they will be closed. In this repository, even if I drag it very fast, I still need to drag it to the bottom of the screen, which makes this feature particularly useless for mobile users, as it is difficult for me to close it using gestures.

Hello @Jackjun724 ! Thanks for opening the issue. We are using the same default values for Android and iOS coming from the implementation in Flutter SDK. However, it is possible to customize these values by extending the WoltModalType class and setting up closeProgressThreshold and minFlingVelocity
