TextLoader class

TextLoader is a text-based loader that animates letters appearing sequentially.

The animation loops infinitely, progressively revealing the text one letter at a time. The animation reverses direction at the end, creating a continuous back-and-forth effect.

Parameters:

  • duration : int - the duration of the forward-and-reverse animation cycle in seconds (default is 2 seconds).
  • textStyle : TextStyle? - the text style applied to the animated text (default is the app's headline style).
  • text : String - the text to be animated (default is "Loading...").

Example:

TextLoader(
  duration: 3,
  text: "Processing...",
  textStyle: TextStyle(
    fontWeight: FontWeight.bold,
    fontSize: 30,
    color: Colors.blueAccent,
  ),
)
