Answer 1

You can copy paste run full code below
Please see working demo below
You can use package https://pub.dev/packages/keyboard_overlay
Step 1: Use with HandleFocusNodesOverlayMixin
Step 2: Use FocusNodeOverlay for focusNode
Step 3: Use GetFocusNodeOverlay and set _focusNodeOverlay = GetFocusNodeOverlay(
Step 4: TextField use TextField(focusNode: _focusNodeOverlay,
code snippet

class _MyHomePageState extends State<MyHomePage>
    with HandleFocusNodesOverlayMixin {
  FocusNodeOverlay _focusNodeOverlay;

  @override
  void initState() {
    _focusNodeOverlay = GetFocusNodeOverlay(
      child: TopKeyboardUtil(
        Container(
          color: Colors.white,
          height: 45,
          width: MediaQueryData.fromWindow(ui.window).size.width,
          child: Row(
            children: [
              GestureDetector(
                child: Icon(Icons.save),
                onTap: () => print("click"),
              ),
             ...
              Spacer(),
              Container(
                width: 60,
                child: Center(
                  child: DoneButtonIos(
                    backgroundColor: Colors.white,
                    textColor: Colors.green,
                    label: 'Post',
                    onSubmitted: () {
                      print("submit");
                    },
                    platforms: ['android', 'ios'],
                  ),

Answer 2

Yes there is a way around in the flutter to achieve this.

1. Create a widget of the toolbar you want to add.
2. Set it visible on input focus.

For reference I am sharing the code how I achieve that.

class InputDoneView extends StatelessWidget {


@override
  Widget build(BuildContext context) {
    return Container(
      width: double.infinity,
      color: Style.lightGrey,
      child: Align(
        alignment: Alignment.topRight,
        child: Padding(
          padding: const EdgeInsets.only(top: 1.0, bottom: 1.0),
          child: CupertinoButton(
            padding: EdgeInsets.only(right: 24.0, top: 2.0, bottom: 2.0),
            onPressed: () {
              FocusScope.of(context).requestFocus(new FocusNode());
            },
            child: Text(
              "Done",
              style: TextStyle(color: Style.primaryColor,fontWeight: FontWeight.normal)
            ),
          ),
        ),
      ),
    );
  }
}

To call this in your main view when input field is focused in and out.

showOverlay(BuildContext context) {
    if (overlayEntry != null) return;
    OverlayState overlayState = Overlay.of(context);
    overlayEntry = OverlayEntry(builder: (context) {
      return Positioned(
          bottom: MediaQuery.of(context).viewInsets.bottom, right: 0.0, left: 0.0, child: InputDoneView());
    });

    overlayState.insert(overlayEntry);
  }

  removeOverlay() {
    if (overlayEntry != null) {
      overlayEntry.remove();
      overlayEntry = null;
    }
  }
