Usage

You can override the duration of animation of single text by setting its duration in each AnimatedTextKit class, also you can set the time of the pause between texts by setting the pause parameter and with this when isRepeatingAnimation is set to true, you can set number of times the animation should repeat with totalRepeatCount. The speed parameter is also included for some classes which sets the delay between the apparition of each characters. Also, the displayFullTextOnTap and stopPauseOnTap parameters have been included for some classes.

TypewriterAnimatedTextKit(
  duration: Duration(milliseconds: 2000),
  totalRepeatCount: 4,
  pause: Duration(milliseconds:  1000),
  text: ["do IT!", "do it RIGHT!!", "do it RIGHT NOW!!!"],
  textStyle: TextStyle(fontSize: 32.0, fontWeight: FontWeight.bold),
  pause: Duration(milliseconds: 1000),
  displayFullTextOnTap: true,
  stopPauseOnTap: true
);

Also, different callbacks are added to each AnimatedTextKit class along with the onTap callback:

  • onNext(int index, bool isLast) – This callback will be called before the next text animation, after the previous one’s pause.
  • onNextBeforePause(int index, bool isLast) – This callback will be called before the next text animation, before the previous one’s pause.
  • onFinished – This callback is called at the end, if the parameter isRepeatingAnimation is set to false.
