Expanded Launch Types

We've significantly expanded the range of supported applications and actions:

• Instagram: LaunchType.instagram - Launch Instagram profiles or content.
• TikTok: LaunchType.tiktok - Launch TikTok profiles or content.
• LinkedIn: LaunchType.linkedin - Launch LinkedIn profiles or content.
• Calendar: LaunchType.calendar - Open calendar apps to create events.
• Share: LaunchType.share - Utilize the native share sheet to share text or files.
• Custom: LaunchType.custom - For any URI scheme not explicitly covered.

Dynamic URI Builders

The package now includes robust internal URI builders that intelligently construct the correct URIs for each LaunchType, handling parameters and encoding automatically. This simplifies usage and reduces the chance of errors.

Multi-Choice Launch Dialogs

For actions that can be handled by multiple applications on a user's device (e.g., opening a map, sharing content, or opening a web link), launchify now supports multi-choice dialogs. This allows users to select their preferred application.

How to use Multi-Choice Dialogs: You can enable this feature using the LaunchOptions class. Pass an instance of LaunchOptions to the options parameter of LaunchLink, LaunchActionButton, or LaunchLinkRow.

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

// Example of launching a map with a multi-choice dialog
LaunchLink
(
type: LaunchType.map,
value: 'New York, NY',
label: 'Open Map with Chooser',
options: LaunchOptions(
useMultiChoiceDialog: true,
dialogTitle: 'Open Map With',
dialogMessage: 'Choose an app to open the map:',
),
)

// Example for sharing content
LaunchLink(
type: LaunchType.share,
shareText: 'Check out this awesome Flutter package!',
shareSubject: 'Launchify Package',
label: 'Share Content',
options: LaunchOptions(
useMultiChoiceDialog: true,
dialogTitle: 'Share With',
dialogMessage
    :
'
Select an app to share:
'
,
)
,
)

• Android: On Android, this will leverage the system's native app chooser dialog.
• iOS: On iOS, a custom bottom sheet dialog will be presented, listing available applications that can handle the URI.

Backward Compatibility

We've ensured that existing implementations of launchify will continue to work without changes. If you're using the older launch method or not providing LaunchOptions, the package will intelligently infer the LaunchType from the provided Uri and attempt to launch it directly, maintaining your current functionality.

App Awareness and Installation Checks

launchify now provides robust app awareness, allowing you to check if a target application is installed before attempting to launch. If the app is not installed, a customizable dialog can be displayed to guide the user.

How to use App Awareness: Configure app awareness using the LaunchOptions class.

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

// Example of launching WhatsApp with app installation check
LaunchLink
(
type: LaunchType.whatsapp,
value: "+923001234567",
label: "Chat on WhatsApp",
options: LaunchOptions(
checkAppInstallation: true, // Enable app installation check
appStoreLink: 'https://apps.apple.com/us/app/whatsapp-messenger/id310633997', // iOS App Store link
// For Android, the package name is used automatically.
appNotInstalledDialogTitle: 'WhatsApp Not Installed',
appNotInstalledDialogMessage: 'It looks like WhatsApp is not installed on your device. Would you like to go to the App Store or open in web?',
fallbackMode: LaunchFallbackMode.prompt, // Prompt user for web fallback
),
)

• checkAppInstallation: Set to true to enable the app installation check.
• appStoreLink: Provide a link to the app store (e.g., Apple App Store, Google Play Store). If the app is not installed, this link will be used in the dialog.
• Android: Uses external_app_launcher to check for app installation via package names.
• iOS: Leverages canLaunchUrl and IosAppLauncher to validate app scheme availability.
• "App Not Installed" Dialog: If the app is not installed, a dialog will be presented with options to:
  • Go to the App Store (if appStoreLink is provided).
  • Open in Web (if a web URI is available and fallbackMode is prompt).
  • Cancel the launch action.

📦 Installation

Add launchify to your pubspec.yaml:

dependencies:
  launchify: ^1.0.4 # Use the latest version
  external_app_launcher: ^3.0.0 # Required for app installation checks

Then run flutter pub get.

Platform Configuration

Since this package uses url_launcher, android_intent_plus, and external_app_launcher, you must follow its configuration steps for each platform:

Android

Add the following to your AndroidManifest.xml (inside <queries>):

<queries>
    <intent>
        <action android:name="android.intent.action.VIEW" />
        <data android:scheme="https" />
    </intent>
    <intent>
        <action android:name="android.intent.action.DIAL" />
    </intent>
    <intent>
        <action android:name="android.intent.action.SENDTO" />
        <data android:scheme="mailto" />
    </intent>
    <intent>
        <action android:name="android.intent.action.VIEW" />
        <data android:scheme="sms" />
    </intent>
    <!-- For multi-choice dialogs and specific app launches -->
    <intent>
        <action android:name="android.intent.action.VIEW" />
        <data android:scheme="instagram" />
    </intent>
    <intent>
        <action android:name="android.intent.action.VIEW" />
        <data android:scheme="tiktok" />
    </intent>
    <intent>
        <action android:name="android.intent.action.VIEW" />
        <data android:scheme="linkedin" />
    </intent>
    <intent>
        <action android:name="android.intent.action.VIEW" />
        <data android:scheme="whatsapp" />
    </intent>
    <intent>
        <action android:name="android.intent.action.VIEW" />
        <data android:scheme="geo" />
    </intent>
    <intent>
        <action android:name="android.intent.action.VIEW" />
        <data android:scheme="google.navigation" />
    </intent>
    <intent>
        <action android:name="android.intent.action.VIEW" />
        <data android:scheme="waze" />
    </intent>
    <intent>
        <action android:name="android.intent.action.EDIT" />
        <data android:mimeType="vnd.android.cursor.item/event" />
    </intent>
    <!-- Add any other custom schemes your app might launch -->
</queries>

iOS

Add the schemes you want to support to your Info.plist. This is crucial for the canLaunch method to work correctly for custom schemes and for the multi-choice dialog to list available apps.

Example ios/Runner/Info.plist entry:

<key>LSApplicationQueriesSchemes</key><array>
<string>https</string>
<string>http</string>
<string>tel</string>
<string>mailto</string>
<string>sms</string>
<string>whatsapp</string>
<string>instagram</string>
<string>tiktok</string>
<string>linkedin</string>
<string>maps</string>
<string>googlemaps</string>
<string>waze</string>
<string>comgooglemaps</string>
<string>baidumap</string>
<string>iosamap</string>
<string>yandexmaps</string>
<string>yandexnavi</string>
<string>citymapper</string>
<string>uber</string>
<string>lyft</string>
<string>moovit</string>
<string>transit</string>
<string>here</string>
<string>tomtomgo</string>
<string>sygiic</string>

🎨 Icon & Image Customization

Launchify supports much more than just Material Icons. You can use SVG, PNG, JPG files from your assets or even from a network URL.

Using Default Icons

By default, LaunchLink shows a context-relevant icon. To disable it:

LaunchLink
(
type: LaunchType.phone,
value: "123456",
showIcon
:
false
, // Removes the icon
)

Using SVG or Asset Images

To use a custom image (e.g., a branded WhatsApp logo):

LaunchLink
(
type: LaunchType.whatsapp,
value: "+923001234567",
customIcon: LaunchIcon.fromAsset('assets/images/whatsapp_logo.svg')
,
)

Using Network Images

LaunchLink
(
type: LaunchType.website,
value: "https://example.com",
customIcon: LaunchIcon.fromNetwork('https://example.com/logo.png')
,
)

LaunchStyle

Provides deep customization for the widgets.

Property	Default (Action Button)
backgroundColor	Theme Primary Color
textColor	White
borderRadius	8.0
isOutlined	false
iconWidth	Derived from fontSize
iconHeight	Derived from fontSize
iconFit	BoxFit.contain

🌍 RTL Support

Launchify is designed for global apps. It automatically detects Directionality.of(context) and:

1. Position icons correctly relative to text.
2. Aligns rows based on LTR/RTL settings.
3. Supports Arabic, Urdu, Hebrew, and other RTL languages out of the box.

🔒 Security

• Always uses canLaunchUrl before attempting a launch. • Supports allowedSchemes to restrict which URLs can be opened. • Parses and validates URIs internally before hand-off to the OS.
