Status Bar Tap

A Flutter package that enables scroll-to-top functionality when tapping the status bar, just like in native iOS apps. Brings familiar iOS behavior to your Flutter app with full customization for both iOS and Android.

Usage

Basic Setup

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

class MyScreen extends StatefulWidget {
  @override
  State<MyScreen> createState() => _MyScreenState();
}

class _MyScreenState extends State<MyScreen> {
  final ScrollController _scrollController = ScrollController();

  @override
  void initState() {
    super.initState();
    WidgetsBinding.instance.addPostFrameCallback((_) {
      final double statusBarHeight = MediaQuery.of(context).padding.top;
      StatusBarTap().initialize(
        config: StatusBarTapConfig(
          enableOnIOS: true,
          enableOnAndroid: true,
          statusBarHeight: statusBarHeight,
        ),
      );
      StatusBarTap().registerScrollController(_scrollController);
    });
  }

  @override
  void dispose() {
    StatusBarTap().unregisterScrollController(_scrollController);
    StatusBarTap().dispose();
    _scrollController.dispose();
    super.dispose();
  }

  @override
  Widget build(BuildContext context) {
    return ListView.builder(
      controller: _scrollController,
      itemBuilder: (context, index) => ListTile(title: Text('Item $index')),
    );
  }
}

Advanced Configuration

WidgetsBinding.instance.addPostFrameCallback((_) {
  final double statusBarHeight = MediaQuery.of(context).padding.top;
  StatusBarTap().initialize(
    config: StatusBarTapConfig(
      enableOnIOS: true,           // Enable on iOS (default: true)
      enableOnAndroid: false,      // Enable on Android (default: false)
      androidTapAreaHeight: 20.0,  // Additional tap area for Android
      statusBarHeight: statusBarHeight,
      scrollDuration: Duration(milliseconds: 400),
      scrollCurve: Curves.fastOutSlowIn,
      debug: true,                 // Enable debug logging
      debugVisual: true,           // Show visual tap area overlay
      onTap: () {
        // Custom callback when status bar is tapped
        print('Status bar tapped!');
      },
    ),
  );
});

Multiple Controllers

// Register multiple scroll controllers
StatusBarTap().registerScrollController(_mainController);
StatusBarTap().registerScrollController(_sidebarController);

// All registered controllers will scroll to top on status bar tap

FAQ

Q: Why doesn't it work on Android by default?
A: Android doesn't expose status bar tap events to apps. The package works around this by detecting taps in an area below the status bar. Set enableOnAndroid: true and adjust androidTapAreaHeight as needed.

Q: Can I use multiple scroll controllers?
A: Yes! Register multiple controllers and they'll all scroll to top on status bar tap.
