Wrap class :
Wrap class is used to align or adjust multiple widgets vertically or horizontally similar to Rows and Columns. It can be adjusted either in form of Row or Column as required. Wrap class automatically align or fit the widgets accordingly in its cross-axis area without displaying an Overflow message similar to Rows and Columns.
Properties :
alignment: this property is used to describe how the children should align in the main axis. Its default value is WrapAlignment.start.
clipBehavior: This property takes in Clip enum as the object and decides whether the content should be clipped or not according to the option.
crossAxisAlignment: this property is used to describe how the children should be aligned relative to each other in the cross-section part. Its default value is WrapCrossAlignment.start .
direction: This property uses a direction as the main axis. By default axis is horizontal and we can change it to vertical by using Axis.verical its value.
runAlignment: this property describes how the run should be placed in the cross axis. Its default value is WrapAlignment.start.
spacing: this property is used to place a space between children in the main axis.
runSpacing: this property is used to place a space between the children along a cross axis.
textDirection: this property is used to arrange the children inside Wrap class in the given direction.
verticalDirection: this property is used to determine the order to lay children out vertically and how to interpret start and end in the vertical direction.
