Answer 1

Yo can set to false the resizeToAvoidBottomInset in your Scaffold()

Like this

return Scaffold(
  resizeToAvoidBottomInset: false,
  body: // ...
  // ...
)

Documentation reference: Scaffold - resizeToAvoidBottomInset

It's beginner level problem. Don't know why most tutorial don't cover this problem before showing TextField Widget.

Column widget is fixed and does not scroll. So change Column to ListView. And do nothing else. The Widget will gain scroll feature and overflow problem will not happen anymore.
