SeparatedColumn class
A widget that arranges its children in a vertical column with separators between them.
The SeparatedColumn
widget takes a list of children and arranges them vertically
in a column, inserting separator widgets between each child based on the provided
separatorBuilder. This enables custom separators between children.
Using the includeFirstSeparator property, separators can be added at the outer edges of the column, determining whether separators are placed above the first child and below the last child in the column.
Example usage:
SeparatedColumn(
includeOuterSeparators: true,
separatorBuilder: (BuildContext context, int index) {
return Container(
height: 2,
color: Colors.grey,
);
},
children: [
Text('One'),
Text('Two'),
Text('Three'),
],
)
The SeparatedColumn
layout properties like mainAxisAlignment, crossAxisAlignment,
and textBaseline can be utilized to customize the alignment and layout of its children
and separators within the column.
