how to set showModalBottomSheet to full height

Question

i use showRoundedModalBottomSheet, how to adjust this modal height till below the appbar?

Answer 1

1. You open class BottomSheet in library of flutter and change maxHeight

from

BoxConstraints getConstraintsForChild(BoxConstraints constraints) {
return BoxConstraints(
  minWidth: constraints.maxWidth,
  maxWidth: constraints.maxWidth,
  minHeight: 0.0,
  maxHeight: constraints.maxHeight * 9.0 / 16.0
);}

to

BoxConstraints getConstraintsForChild(BoxConstraints constraints) {
return BoxConstraints(
  minWidth: constraints.maxWidth,
  maxWidth: constraints.maxWidth,
  minHeight: 0.0,
  maxHeight: constraints.maxHeight
);}

2. You can create a new class with other name and copy source code from class BottomSheet and change maxHeight
