Heart Overlay Widget 💖

The HeartOverlay widget can be used to create a fun and interactive overlay that displays a heart animation when the user taps on the screen. It can be used as a decorative element for apps that require a playful or romantic touch, such as dating apps, greeting card apps, or social media apps.

A screen record will be provided soon

Features 🤩

• Displays a heart-shaped icon overlaid on top of eachother when tapped in quick succession while shrinking and fading at the same time just like social media apps (i.e Tik tok, Instagram).💖
• The displayed icon can be any widget and can be styled however you like.🤗
• The overlay background can be customized however you like.✏️

Getting started 🤗

To use this package, add heart_overlay as a dependency in your pubspec.yaml file.

Then import

    import 'package:heart_overlay/heart_overlay.dart';

Usage 🧐

Simple usage:

    HeartOverlay();

More customizability:

With Icon:

    HeartOverlay(
        icon: Icon(
          Icons.abc,
          color: Colors.cyan,
          size: 40,
        ),
        controller: heartOverlayController, // [HeartOverlayController] - check out the example to see how it's used
        verticalOffset: 10,  // Vertical Offset from tap position
        horizontalOffset: 10,  // Horizontal Offset from tap position
        duration: Duration(milliseconds: 800), // Icon to stay on screen duration 
        tapDownType: TapDownType.double, // The animation trigger type
        cacheExtent: 10, // The cache extent
        splashAnimationDetails: const SplashAnimationDetails(
            enableSplash: true, // Enables a light weight splash animation to the icon provided
            animationDuration: Duration(seconds: 3), // Animation duration of the splash icon
        ), 
        onPressed: (numberOfHearts) {
            // Do something with the number of hearts shown or do something whenever the icon appears
        },
        child: Image.asset('assets/image.png'), // Overlay container background
    ),

or

With any Widget:

    HeartOverlay(
        icon: const Text('✌️'),
        size: 60,
        controller: heartOverlayController, // [HeartOverlayController] - check out the example to see how it's used
        // It might be nesessary to add vertical and horizontal offset when using other types of widget instead of [Icon]s to accurately position the widgets
        verticalOffset: 20,  // Vertical Offset from tap position
        horizontalOffset: -10,  // Horizontal Offset from tap position
        duration: Duration(milliseconds: 800), // Icon to stay on screen duration 
        tapDownType: TapDownType.single, // The animation trigger type
        cacheExtent: 10, // The cache extent
        onPressed: (numberOfHearts) {
            // Do something with the number of hearts shown or do something whenever the icon appears
        },
        child: Image.asset('assets/image.png'), // Overlay container background
    ),

Common Errors and Issues🐛

Errors

If you get errors like forces infinite height/forces infinite width when used in a Column, Row or Flex widget:

Specify a desired height/width to the HeartOverlay widget.

OR

Wrap the HeartOverlay in an Expanded/Flexible widget.

Note that: And if an Expanded/Flexible widget is used, height/width properites are basically useless.

Issues

As of HeartOverlay Version: 1.2.0, Widget support is available as shown here, though you might have to fiddle with the vertical and horizontal offsets to precisely align the widget to its tap position.

As of HeartOverlay Version: 1.3.0, Splash support is available as shown here, though it can only support [Icon] types.
