Hero Explained | Flutter for Android Developers

What’s Hero?

The Hero class is a widget in Flutter that enables hero animations, allowing a widget to transition smoothly between two routes. It is particularly useful for creating visually appealing transitions when navigating between screens. Key properties include ‘tag’, which identifies the hero, and ‘child’, which is the widget that will animate.

Hero explained for Android Developers

For Android developers familiar with Activity transitions, the Hero class serves a similar purpose by providing a way to animate shared elements between screens. In Android, you might use shared element transitions, while in Flutter, the Hero widget handles this seamlessly. The concept of tagging the widgets to identify which ones to animate is akin to using transition names in Android.

Example Code

Here is an example of how to use Hero:

Hero(
  tag: 'hero-tag',
  child: Image.network('https://example.com/image.png'),
),

Hero Remarks
