Flutter - comment ajouter un bouton terminé dans le clavier numérique dans flutter

J'essaie d'ajouter un bouton terminé dans une entrée de type numérique pour un TextFormField en flutter, mais je n'ai pas pu le faire.Veuillez aider avec une solution.

code:

TextFormField(
          key: Key(keyValue),
          initialValue: valueBuilder,
          onSaved: (text) {
            fieldsController.text = text.trim();
          },
          inputFormatters: [inputFormatters],
          keyboardType: TextInputType.phoneNumber,)

Je veux créer un clavier comme this . Pour le champ du formulaire de saisie de texte.

Utilisation:

    import  'package:flutter/material.Dart';
    import  'package:keyboard_actions/keyboard_actions.Dart';

     //...
      FocusNode _nodeText1 = FocusNode();
      FocusNode _nodeText2 = FocusNode();
      FocusNode _nodeText3 = FocusNode();
      FocusNode _nodeText4 = FocusNode();
      FocusNode _nodeText5 = FocusNode();

     @override
      Widget build(BuildContext context) {
        return Scaffold(
          appBar: AppBar(
            title: Text("Keyboard Actions Sample"),
          ),
          body: FormKeyboardActions(
            keyboardActionsPlatform: KeyboardActionsPlatform.ALL, //optional
            keyboardBarColor: Colors.grey[200], //optional
            nextFocus: true, //optional
            actions: [
              KeyboardAction(

                focusNode: _nodeText2,
                closeWidget: IconButton(
