          You can achieve it by checking for keyboard visibility using viewInsets and hide fab based on it.



          Example:



          import 'package:flutter/material.dart';

          void main() {
          runApp(new MaterialApp(
          title: "Example",
          home: new FabHideOnKeyboard(),
          ));
          }

          class FabHideOnKeyboard extends StatefulWidget {
          @override
          _FabHideOnKeyboardState createState() => new _FabHideOnKeyboardState();
          }

          class _FabHideOnKeyboardState extends State<FabHideOnKeyboard> {
          @override
          Widget build(BuildContext context) {
          final bool showFab = MediaQuery.of(context).viewInsets.bottom==0.0;
          return Scaffold(
          resizeToAvoidBottomPadding: true,
          body:Container(
          alignment: Alignment.center,
          child: Column(
          mainAxisAlignment: MainAxisAlignment.center,
          children: <Widget>[
          Text("TextField:"),
          TextField()
          ],
          ),
          ),
          floatingActionButton: showFab?Icon(Icons.add):null,
          );
          }
          }


          Hope that helped!
