wrap_and_more

Description:

wrap and more

wrap_and_more #
The wrap_and_more library provides a custom Flutter widget called WrapAndMore that allows you to display child widgets within a Wrap layout and handle cases where the number of children exceeds a specified maximum row count.
The WrapAndMore widget lays out its children in a Wrap widget and
displays the specified overflowWidget when the children exceed the
maximum number of rows specified by the maxRow parameter. The number
of children to display is automatically determined based on the available
space within the Wrap.
You can use this widget to achieve:

Limiting the number of rows
Get the count of the remaining children
