A widget where each fragment has their own navigation history inside the bottom navigation bar
Getting Started #
1. import bottommultinavigationbar #
import 'package:bottommultinavigationbar/bottommultinavigationbar.dart';
2. Create a list of PageNavigators: #
var pages = [
PageNavigator(
bottomNavigationIcon: Icon(Icons.ac_unit),
bottomNavigationText: "Page 1",
initialRoute: "/page2",
onGenerateRoute: (settings) {
if(settings.name == PageNavigator.home)
return MaterialPageRoute(builder: (_) => Test(test:"Page 1 - 1",index: 0,));
if(settings.name == "/page2")
return MaterialPageRoute(builder: (_) => Test(test:"Page 1 - 2",index: 0));
}
),
PageNavigator(
bottomNavigationIcon: Icon(Icons.ac_unit),
bottomNavigationText: "Page 2",
onGenerateRoute: (settings) {
if(settings.name == PageNavigator.home)
return MaterialPageRoute(builder: (_) => Test(test:"Page 2 - 1",index: 1,));
if(settings.name == "/page2-2")
return MaterialPageRoute(builder: (_) => Test(test:"Page 2 - 2",index: 1,));
}
),
];
Be sure that you use "/" in your namings like "/page1". PageNavigator.home represents the home page of the fragment. From there the navigator will navigate to your pages inside of the fragment without leaving the bottom navigation view. With the "initialRoute" attribute you can specify a different start point for each of your fragment.
3. Use the BottomMultiNavigationBar Widget #
@override
Widget build(BuildContext context) {
return BottomMultiNavigationBar(
index: myCounter
pageNavigators: pages,
onIndexChanged: (index) {
setState({
myCounter = index
})
},
);
}
4. Navigate #
You can use the Navigator.of(context).pushNamed() as usual
Navigator.of(context).pushNamed("/page2")
With passing data:
//push your data
Navigator.of(context).pushNamed("/page2-2",arguments: "Test data")
//in your PageNavigator
PageNavigator(
bottomNavigationIcon: Icon(Icons.ac_unit),
bottomNavigationText: "Page 2",
onGenerateRoute: (settings) {
if(settings.name == PageNavigator.home)
return MaterialPageRoute(builder: (_) => Test(test: "page2-1",index: 1,));
if(settings.name == "/page2-2")
if(settings.arguments is String)
return MaterialPageRoute(builder: (_) => Test(test: settings.arguments,index: 1,));
//else error handling
}
),
Using the FlutterIntent navigation system #
This system is especially developed for this package and imitates the intent system of the Android Framework. Please be aware that you use only one of the provided navigation system. So if you want to use the onGenerateRoute attribute the flutterIntentService has to be null and vice versa.
1. Use the flutterIntentService attribute of the PageNavigator class #
PageNavigator(
bottomNavigationIcon: Icon(Icons.ac_unit),
bottomNavigationText: "Page 1",
flutterIntentService: FlutterIntentService(
onIntent: (intent) {
if(intent.name == "/")
return Test(name: intent.getStringExtra("str_page_name"));
if(intent.name == "/page2")
//we now that we get a boolean
return TestBool(isTrue: intent.getBoolExtra("bool_value"));
}
)
),
The intent which is passed as parameter holds the data. From there you can get your data like in the example above.
2. Send an intent #
For sending an intent use the FlutterIntent() class:
FlutterIntent(context: context,name: "/page2")
..putExtra("bool_value",true)
..startActivity();
Don't forget to call the startActivity in the end. This will start the next activity and pass your data to the next page which you defined in the PageNavigator in step 1.
