FlexSplitColumn class final

A widget that takes a list of children and lays them out in a column where each child has a flexible height.

Each child in children must have an accompanying header in headers. Since each header must be a PreferredSizeWidget, it is common to use the shared widgets AreaPaneHeader or BlankHeader for the column headers.

The user can customize the amount of space allocated to each child by clicking and dragging the headers that separate the children.

The constructor's initialFractions parameter defines how much space to give each child when building this widget.

The constructor's minSizes defines the minimum size that each child can be set to when adjusting the sizes of the children.
