Usage
First of all you need to import our package.
import 'package:starlight_base_appbar/starlight_base_appbar.dart';
And then you can use easily.
Example
import 'package:flutter/material.dart';
import 'package:starlight_base_appbar/starlight_base_appbar.dart';
void main() {
runApp(const MyApp());
}
class MyAppBar extends StarlightBaseAppBar {
@override
Widget builder(BuildContext context) {
return Container();
}
}
class MyApp extends StatelessWidget {
const MyApp({Key? key}) : super(key: key);
// This widget is the root of your application.
@override
Widget build(BuildContext context) {
return MaterialApp(
title: 'Flutter Demo',
theme: ThemeData(
// This is the theme of your application.
//
// Try running your application with "flutter run". You'll see the
// application has a blue toolbar. Then, without quitting the app, try
// changing the primarySwatch below to Colors.green and then invoke
// "hot reload" (press "r" in the console where you ran "flutter run",
// or simply save your changes to "hot reload" in a Flutter IDE).
// Notice that the counter didn't reset back to zero; the application
// is not restarted.
primarySwatch: Colors.blue,
),
home: const MyHomePage(title: 'Flutter Demo Home Page'),
);
}
}
class MyHomePage extends StatefulWidget {
const MyHomePage({Key? key, required this.title}) : super(key: key);
// This widget is the home page of your application. It is stateful, meaning
// that it has a State object (defined below) that contains fields that affect
// how it looks.
// This class is the configuration for the state. It holds the values (in this
// case the title) provided by the parent (in this case the App widget) and
// used by the build method of the State. Fields in a Widget subclass are
// always marked "final".
final String title;
@override
State<MyHomePage> createState() => _MyHomePageState();
}
class _MyHomePageState extends State<MyHomePage> {
int _counter = 10;
bool _isLoading = false;
@override
Widget build(BuildContext context) {
// This method is rerun every time setState is called, for instance as done
// by the _incrementCounter method above.
//
// The Flutter framework has been optimized to make rerunning build methods
// fast, so that you can just rebuild anything that needs updating rather
// than having to individually change instances of widgets.
return Scaffold(
appBar: MyAppBar(),
body: StarlightCallbackListView(
invokeWhen: (double percent) {
if (_isLoading) return;
if (percent > 80) {
_isLoading = true;
Future.delayed(const Duration(seconds: 3), () {
setState(() {
_counter += 10;
_isLoading = false;
});
});
}
},
count: _counter,
builder: (context, index) {
return Container(
width: double.infinity,
height: 100,
margin: const EdgeInsets.symmetric(vertical: 10),
color: Colors.green,
alignment: Alignment.center,
child: Text(index.toString()),
);
},
),
// This trailing comma makes auto-formatting nicer for build methods.
);
}
