TypewriterAnimatedText text not centered in screen

When I use TypewriterAnimatedText animation, I can not have the text horizontally centered to the screen.

Look at the TypewriterAnimatedText widget in the package to understand its layout. The issue is about horizontal centering; check the alignment properties and how the widget is used in the example. Compare with other animated text widgets that center correctly. Test changes in the example app to see the text centered as shown in the second image.
