DraggableBottomSheet class

Draggable bottom sheet based on DraggableScrollableSheet

This widget can be dragged along the vertical axis between its minChildSize, which defaults to 0.2 and maxChildSize, which defaults to 1.0. The initialChildSize defaults to 0.6 These sizes are percentages of the height of the parent container. When running on web initialChildSize is equal to maxChildSize since drag is not supported

minFocusableExtent defines the minimum extent within the content can be focused, defaults to 0.5. This means that if you scroll down the BottomSheet lower that the 50% of the container height, the current focus is cleared and the content will not be focusable until the extent returns over the threshold. Setting this value to 0 means disabling focus check and content will be always focusable

If updateInsets is true, the bottom inset of MediaQuery will be updated as long as the extent changes. This means that if you are using a Scaffold inside this BottomSheet with Scaffold.resizeToAvoidBottomInset true it will automatically resized with a fluid animation. You may have to wrap that scaffold body with a SingleChildScrollView with NeverScrollableScrollPhysics to avoid bottom overflow when scrolling down the BottomSheet When running on web this field is ignored since drag is not supported

builder allows you to build the content basing on DraggableScrollableNotification
