openDrawer method

void openDrawer()

Opens the Drawer (if any).

If the scaffold has a non-null Scaffold.drawer, this function will cause the drawer to begin its entrance animation.

Normally this is not needed since the Scaffold automatically shows an appropriate IconButton, and handles the edge-swipe gesture, to show the drawer.

To close the drawer, use either ScaffoldState.closeDrawer or Navigator.pop.

See Scaffold.of for information about how to obtain the ScaffoldState.
