Custom navigator

A flutter package that makes it easy to create your own navigator anywhere in the widget tree.

A common use for such widget is when you need to implement an "Always presenting bottom navigation bar"

Getting Started

First you need to add the package to your pubspec.yaml file.

Custom scaffold

CustomScaffold is a stateful widget that uses the CustomNavigator to to handle item transition of [BottomNavigationBar] with nested navigation while keeping the [BottomNavigationBar] visible!

Usage

// Here's the custom scaffold widget
// It takes a normal scaffold with mandatory bottom navigation bar
// and children who are your pages
CustomScaffold(
      scaffold: Scaffold(
        bottomNavigationBar: BottomNavigationBar(
          items: _items,
        ),
      ),

      // Children are the pages that will be shown by every click
      // They should placed in order such as
      // `page 0` will be presented when `item 0` in the [BottomNavigationBar] clicked.
      children: <Widget>[
        Page('0'),
        Page('1'),
        Page('2'),
      ],

      // Called when one of the [items] is tapped.
      onItemTap: (index) {},
    );

See the custom_scaffold_example for more details

Custom navigator

The CustomNavigator is fairly easy to use

Usage

CustomNavigator(
        home: YourChildWidget(),
        //Specify your page route [PageRoutes.materialPageRoute] or [PageRoutes.cupertinoPageRoute]
        pageRoute: PageRoutes.materialPageRoute,
      );

Then you can call it using the same old Navigator.of(context)

Options

• you can specify Named routes exactly like in MaterialApp.

if you want to use the default [Navigator] you need to specify a [GlobalKey] to your [MaterialApp] and use it navigatorKey.currentState

See the example for more details.
