Listening events

import 'package:flutter/cupertino.dart';
import 'package:window_manager/window_manager.dart';

class HomePage extends StatefulWidget {
  @override
  _HomePageState createState() => _HomePageState();
}

class _HomePageState extends State<HomePage> with WindowListener {
  @override
  void initState() {
    windowManager.addListener(this);
    super.initState();
  }

  @override
  void dispose() {
    windowManager.removeListener(this);
    super.dispose();
  }

  @override
  Widget build(BuildContext context) {
    // ...
  }

  @override
  void onWindowEvent(String eventName) {
    print('[WindowManager] onWindowEvent: $eventName');
  }

  @override
  void onWindowClose() {
    // do something
  }

  @override
  void onWindowFocus() {
    // do something
  }

  @override
  void onWindowBlur() {
    // do something
  }

  @override
  void onWindowMaximize() {
    // do something
  }

  @override
  void onWindowUnmaximize() {
    // do something
  }

  }
}

Quit on close

If you need to use the hide method, you need to disable QuitOnClose.

macOS

Change the file macos/Runner/AppDelegate.swift as follows:

import Cocoa
import FlutterMacOS

@NSApplicationMain
class AppDelegate: FlutterAppDelegate {
  override func applicationShouldTerminateAfterLastWindowClosed(_ sender: NSApplication) -> Bool {
-    return true
+    return false
  }
}

Confirm before closing

import 'package:flutter/cupertino.dart';
import 'package:window_manager/window_manager.dart';

class HomePage extends StatefulWidget {
  @override
  _HomePageState createState() => _HomePageState();
}

class _HomePageState extends State<HomePage> with WindowListener {
  @override
  void initState() {
    windowManager.addListener(this);
    _init();
    super.initState();
  }

  @override
  void dispose() {
    windowManager.removeListener(this);
    super.dispose();
  }

  void _init() async {
    // Add this line to override the default close handler
    await windowManager.setPreventClose(true);
    setState(() {});
  }

  @override
  Widget build(BuildContext context) {
    // ...
  }

  @override
  void onWindowClose() async {
    bool _isPreventClose = await windowManager.isPreventClose();
    if (_isPreventClose) {
      showDialog(
        context: context,
        builder: (_) {
          return AlertDialog(
            title: Text('Are you sure you want to close this window?'),
            actions: [
              TextButton(
                child: Text('No'),
                onPressed: () {
                  Navigator.of(context).pop();
                },
              ),
              TextButton(
                child: Text('Yes'),
                onPressed: () {
                  Navigator.of(context).pop();
                  await windowManager.destroy();
                },
              ),
            ],
          );
        },
      );
    }
  }
}

Hidden at launch

macOS

Change the file macos/Runner/MainFlutterWindow.swift as follows:

import Cocoa
import FlutterMacOS
+import window_manager

class MainFlutterWindow: NSWindow {
    override func awakeFromNib() {
        let flutterViewController = FlutterViewController.init()
        let windowFrame = self.frame
        self.contentViewController = flutterViewController
        self.setFrame(windowFrame, display: true)

        RegisterGeneratedPlugins(registry: flutterViewController)

        super.awakeFromNib()
    }

+    override public func order(_ place: NSWindow.OrderingMode, relativeTo otherWin: Int) {
+        super.order(place, relativeTo: otherWin)
+        hiddenWindowAtLaunch()
+    }
}

Windows

Change the file windows/runner/win32_window.cpp as follows:

bool Win32Window::CreateAndShow(const std::wstring& title,
                                const Point& origin,
                                const Size& size) {
  ...                              
  HWND window = CreateWindow(
-      window_class, title.c_str(), WS_OVERLAPPEDWINDOW | WS_VISIBLE,
+      window_class, title.c_str(),
+      WS_OVERLAPPEDWINDOW, // do not add WS_VISIBLE since the window will be shown later
      Scale(origin.x, scale_factor), Scale(origin.y, scale_factor),
      Scale(size.width, scale_factor), Scale(size.height, scale_factor),
      nullptr, nullptr, GetModuleHandle(nullptr), this);

Make sure to call setState once on the onWindowFocus event.

import 'package:flutter/cupertino.dart';
import 'package:window_manager/window_manager.dart';

class HomePage extends StatefulWidget {
  @override
  _HomePageState createState() => _HomePageState();
}

class _HomePageState extends State<HomePage> with WindowListener {
  @override
  void initState() {
    windowManager.addListener(this);
    super.initState();
  }

  @override
  void dispose() {
    windowManager.removeListener(this);
    super.dispose();
  }

  @override
  Widget build(BuildContext context) {
    // ...
  }

  @override
  void onWindowFocus() {
    // Make sure to call once.
    setState(() {});
    // do something
  }
}

Use this package as a library

Depend on it

Run this command:

With Flutter:

 $ flutter pub add window_manager

This will add a line like this to your package's pubspec.yaml (and run an implicit flutter pub get):

dependencies:
  window_manager: ^0.2.6

Alternatively, your editor might support flutter pub get. Check the docs for your editor to learn more.

Import it

Now in your Dart code, you can use:

import 'package:window_manager/window_manager.dart';

example/lib/main.dart

import 'package:flutter/material.dart';
import 'package:bot_toast/bot_toast.dart';
import 'package:window_manager/window_manager.dart';

import './pages/home.dart';
import 'themes/themes.dart';
import 'utilities/utilities.dart';

void main() async {
  WidgetsFlutterBinding.ensureInitialized();
  await windowManager.ensureInitialized();

  WindowOptions windowOptions = WindowOptions(
    size: Size(800, 600),
    center: true,
    backgroundColor: Colors.transparent,
    skipTaskbar: false,
    titleBarStyle: TitleBarStyle.hidden,
  );
  windowManager.waitUntilReadyToShow(windowOptions, () async {
    await windowManager.show();
    await windowManager.focus();
  });

  runApp(MyApp());
}

class MyApp extends StatefulWidget {
  @override
  _MyAppState createState() => _MyAppState();
}

class _MyAppState extends State<MyApp> {
  ThemeMode _themeMode = ThemeMode.light;

  @override
  void initState() {
    sharedConfigManager.addListener(_configListen);
    super.initState();
  }

  @override
  void dispose() {
    sharedConfigManager.removeListener(_configListen);
    super.dispose();
  }

  void _configListen() {
    _themeMode = sharedConfig.themeMode;
    setState(() {});
  }

  @override
  Widget build(BuildContext context) {
    final virtualWindowFrameBuilder = VirtualWindowFrameInit();
    final botToastBuilder = BotToastInit();

    return MaterialApp(
      debugShowCheckedModeBanner: false,
      theme: lightThemeData,
      darkTheme: darkThemeData,
      themeMode: _themeMode,
      builder: (context, child) {
        child = virtualWindowFrameBuilder(context, child);
        child = botToastBuilder(context, child);
        return child;
      },
      navigatorObservers: [BotToastNavigatorObserver()],

Google's Flutter 1.20 stable announced with new features - Navoki

Flutter Google cross-platform UI framework has released a new version 1.20 stable.

Flutter is Google’s UI framework to make apps for Android, iOS, Web, Windows, Mac, Linux, and Fuchsia OS. Since the last 2 years, the flutter Framework has already achieved popularity among mobile developers to develop Android and iOS apps. In the last few releases, Flutter also added the support of making web applications and desktop applications.

Last month they introduced the support of the Linux desktop app that can be distributed through Canonical Snap Store(Snapcraft), this enables the developers to publish there Linux desktop app for their users and publish on Snap Store.  If you want to learn how to Publish Flutter Desktop app in Snap Store that here is the tutorial.

Flutter 1.20 Framework is built on Google’s made Dart programming language that is a cross-platform language providing native performance, new UI widgets, and other more features for the developer usage.

Here are the few key points of this release:

Performance improvements for Flutter and Dart

In this release, they have got multiple performance improvements in the Dart language itself. A new improvement is to reduce the app size in the release versions of the app. Another performance improvement is to reduce junk in the display of app animation by using the warm-up phase.

sksl_warm-up

If your app is junk information during the first run then the Skia Shading Language shader provides for pre-compilation as part of your app’s build. This can speed it up by more than 2x.

Added a better support of mouse cursors for web and desktop flutter app,. Now many widgets will show cursor on top of them or you can specify the type of supported cursor you want.

Autofill for mobile text fields

Autofill was already supported in native applications now its been added to the Flutter SDK. Now prefilled information stored by your OS can be used for autofill in the application. This feature will be available soon on the flutter web.

flutter_autofill

A new widget for interaction

InteractiveViewer is a new widget design for common interactions in your app like pan, zoom drag and drop for resizing the widget. Informations on this you can check more on this API documentation where you can try this widget on the DartPad. In this release, drag-drop has more features added like you can know precisely where the drop happened and get the position.

Updated Material Slider, RangeSlider, TimePicker, and DatePicker

In this new release, there are many pre-existing widgets that were updated to match the latest material guidelines, these updates include better interaction with Slider and RangeSlider, DatePicker with support for date range and time picker with the new style.

flutter_DatePicker

New pubspec.yaml format

Other than these widget updates there is some update within the project also like in pubspec.yaml file format. If you are a flutter plugin publisher then your old pubspec.yaml  is no longer supported to publish a plugin as the older format does not specify for which platform plugin you are making. All existing plugin will continue to work with flutter apps but you should make a plugin update as soon as possible.

Preview of embedded Dart DevTools in Visual Studio Code

Visual Studio code flutter extension got an update in this release. You get a preview of new features where you can analyze that Dev tools in your coding workspace. Enable this feature in your vs code by _dart.previewEmbeddedDevTools_setting. Dart DevTools menu you can choose your favorite page embed on your code workspace.

Network tracking

The updated the Dev tools comes with the network page that enables network profiling. You can track the timings and other information like status and content type of your** network calls** within your app. You can also monitor gRPC traffic.

Generate type-safe platform channels for platform interop

Pigeon is a command-line tool that will generate types of safe platform channels without adding additional dependencies. With this instead of manually matching method strings on platform channel and serializing arguments, you can invoke native class and pass nonprimitive data objects by directly calling the Dartmethod.

There is still a long list of updates in the new version of Flutter 1.2 that we cannot cover in this blog. You can get more details you can visit the official site to know more. Also, you can subscribe to the Navoki newsletter to get updates on these features and upcoming new updates and lessons. In upcoming new versions, we might see more new features and improvements.

You can get more free Flutter tutorials you can follow these courses:
