resizeToAvoidBottomInset property Null safety
If true the body and the scaffold's floating widgets should size
themselves to avoid the onscreen keyboard whose height is defined by the
ambient MediaQuery's MediaQueryData.viewInsets
For example, if there is an onscreen keyboard displayed above the scaffold, the body can be resized to avoid overlapping the keyboard, which prevents widgets inside the body from being obscured by the keyboard.
Defaults to true.
