Answer 1

Here You can use flutter flutter_statusbar_manager 1.0.2 lib


Flutter Statusbar Manager, lets you control the status bar color, style (theme), visibility, and translucent properties across iOS and Android. With some added bonus for Android to control the Navigation Bar.


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

import 'package:flutter/services.dart';

void main() => runApp(new MyApp());

class MyApp extends StatefulWidget {
  MyApp();

  factory MyApp.forDesignTime() {
    // TODO: add arguments
    return new MyApp();
  }

  @override
  _MyAppState createState() => new _MyAppState();
}

class _MyAppState extends State {
  double _statusBarHeight = 0.0;
  bool _statusBarColorAnimated = false;
  Color _statusBarColor = Colors.black;
  double _statusBarOpacity = 1.0;
  bool _statusBarHidden = false;
  StatusBarAnimation _statusBarAnimation = StatusBarAnimation.NONE;
  StatusBarStyle _statusBarStyle = StatusBarStyle.DEFAULT;
  bool _statusBarTranslucent = false;
  bool _loadingIndicator = false;
  bool _fullscreenMode = false;

  bool _navBarColorAnimated = false;
  Color _navBarColor = Colors.black;
  NavigationBarStyle _navBarStyle = NavigationBarStyle.DEFAULT;

  @override
  void initState() {
    super.initState();
    initPlatformState();
  }

  // Platform messages are asynchronous, so we initialize in an async method.
  Future initPlatformState() async {
    double statusBarHeight;
    // Platform messages may fail, so we use a try/catch PlatformException.
    try {
      statusBarHeight = await FlutterStatusbarManager.getHeight;
    } on PlatformException {
      statusBarHeight = 0.0;
    }
    if (!mounted) return;

    setState(() {
      _statusBarHeight = statusBarHeight;
    });
  }

  Widget renderTitle(String text) {
    final textStyle = TextStyle(fontSize: 18.0, fontWeight: FontWeight.bold);
    return Text(text, style: textStyle);
  }

  void colorBarChanged(Color val) {
    this.setState(() {
      _statusBarColor = val;
    });
    updateStatusBar();
  }

  void updateStatusBar() {

        _statusBarColor.withOpacity(_statusBarOpacity),

    updateNavBar();
  }

  void updateNavBar() {

        animated: _navBarColorAnimated);
  }

  void navigationBarStyleChanged(NavigationBarStyle val) {
    this.setState(() {

    FlutterStatusbarManager.setNavigationBarStyle(val);
  }
