resizeToAvoidBottomInset property
If true the content 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 bottom property.
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.
Implementation
final bool resizeToAvoidBottomInset;
