ABOUT DefaultTextStyle

**Is your feature request related to a problem? Please describe.**
A clear and concise description of what the problem is. Ex. I'm always frustrated when [ For defaultTextStyle 2 child widgets are needed some parent widgets like sliverboxadapter does not take multiple child widgets so every animated text needs individual textstyle]

**Describe the solution you'd like**
Keeping DefaultTextStyle inside AnimatedTextKit before animatedTexts:[] like

AnimatedTextKit( DefaultTextStyle()
animatedTexts:[]
)

**Describe alternatives you've considered**
used textstyle individually for multiple texts

**Additional context**
Add any other context or screenshots about the feature request here.

Look at the AnimatedTextKit widget's constructor in the source code to understand how animatedTexts are currently structured. Examine how DefaultTextStyle interacts with child widgets in Flutter. The goal is to modify AnimatedTextKit to accept a DefaultTextStyle before the animatedTexts list, allowing a single text style to apply to multiple animated texts without needing individual TextStyle for each.
