@aagarwal1012 Facing the same issue. I am unable to update the animated text using setState method.

Widget build(context) {

    Widget dynamicResponse = Container(
      padding: const EdgeInsets.all(32),
      child: TyperAnimatedTextKit(
        isRepeatingAnimation: false,
        text: [
          responseText,
        ],
      ),
    );

    return Scaffold(
      body: ListView(
        children: [
          dynamicResponse
        ],
      ),
    );

   updateText() {
    setState(() {
      responseText = newValue();
    });
  }

updateText updates the value to responseText but the changes are not reflected to the widget.

For anyone who is still getting the issue ... make sure you pass in a ValueKey as the key to your TyperAnimatedTextKit ... then when you would setState it would update the widget for you

This solution works perfectly for flutter projects using GetX package using Obx instead of setState.
