direction Axis Defines if indicator is horizontal or vertical. Axis.horizontal
progressDirection TextDirection Defines if steps grow from left-to-right / top-to-bottom TextDirection.ltr or right-to-left / bottom-to-top TextDirection.rtl. TextDirection.ltr
size double Size of the indicator (height if direction is Axis.horizontal, width if Axis.vertical). 4.0
padding double Spacing, left-right if horizontal, top-bottom if vertical, of each step. 2.0
fallbackLength double Length of the progress indicator in case the main axis (based on direction attribute) has no size limit i.e. double.infinity. 100.0
