flutter_emoji_feedback

A fully customizable widget to receive feedback from your users. Useful to get the user's mood, evaluate their experience, and more!

📺 What's new?

You can now use animated lottie files (json files only) for emoji presets, or the provided notoAnimatedEmojis preset. (see #3)

⚠️ Breaking changes

• rating is now no longer needed, the package handles that internally. If you need to set an intial rating, see Parameters.
• Presets must be defined as either a StaticEmojiPreset or a AnimatedEmojiPreset, see Defining Presets

🎨 Defining presets

You can easily create presets using the StaticEmojiPreset and AnimatedEmojiPreset, which hold the emojis.

// Defining a static emoji preset using SVG files
// Replace the `image` with your SVG file path
const myStaticEmojiPreset = StaticEmojiPreset([
  StaticEmoji(
    image: 'assets/images/emoji1.svg',
    value: 1,
  ),
  StaticEmoji(
    image: 'assets/images/emoji2.svg',
    value: 2,
  ),
  StaticEmoji(
    image: 'assets/images/emoji3.svg',
    value: 3,
  ),
  StaticEmoji(
    image: 'assets/images/emoji4.svg',
    value: 4,
  ),
  StaticEmoji(
    image: 'assets/images/emoji5.svg',
    value: 5,
  ),
]);

// Defining an animated emoji preset using Lottie files
// Replace the `animation` with the path to your Lottie file
const myAnimatedEmojiPreset = AnimatedEmojiPreset([
  AnimatedEmoji(
    animation: 'assets/animations/emoji1.json',
    value: 1
  ),
  AnimatedEmoji(
    animation: 'assets/animations/emoji2.json',
    value: 2
  ),
  AnimatedEmoji(
    animation: 'assets/animations/emoji3.json',
    value: 3
  ),
  AnimatedEmoji(
    animation: 'assets/animations/emoji4.json',
