Issue while using key

[jamesderlin]

@pedromassango Is it not a problem that TitledBottomNavigationBar does both super(key: key) and SafeArea(child: Container(key: widget.key,? Seems like that might be a bad thing to do with a GlobalKey?

[pedromassango]

it seems that you are tying to reuse a key. Keys must be unique across the app.

See the last line's cooment:

" A GlobalKey can only be specified on one widget at a time in the widget tree"

@pedromassango no, i am creating key in stateful widget and using it only inside navigation bar. Still i'm out of clue why it is showing error.

[pedromassango]

As the message says, you are using it more than once

@pedromassango Here's my code please have a look:

import 'package:flutter/material.dart';
import 'package:titled_navigation_bar/titled_navigation_bar.dart';

class TesterPage extends StatefulWidget {
  @override
  _TesterPageState createState() => _TesterPageState();
}

class _TesterPageState extends State<TesterPage> {
  final GlobalKey _navigationBarKey = GlobalKey();
  @override
  Widget build(BuildContext context) {
    return Scaffold(
      bottomNavigationBar: TitledBottomNavigationBar(
        key: _navigationBarKey,
        onTap: (int index) {
          print(index.toString());
        },
        items: [
          TitledNavigationBarItem(title: 'Home', icon: Icons.home),
          TitledNavigationBarItem(title: 'Help', icon: Icons.help),
          TitledNavigationBarItem(title: 'Account', icon: Icons.person),
        ],
      ),
      body: Center(
        child: RaisedButton(
          child: Text("Test"),
          onPressed: () {
            final TitledBottomNavigationBar navigationBar = _navigationBarKey.currentWidget;
            navigationBar.onTap(1);
          },
        ),
      ),
    );
  }
}

[pedromassango]

Thanks @jamesderlin. I fixed it on the latest version

[pedromassango]

@sukhcha-in are you using any state management pattern like Bloc or Redux?

[sukhcha-in]

@pedromassango no, i am just using in built state functions.

@pedromassango Thanks for recent update :) solved this without even using a key.
