Hi @M123-dev Could Please review it

[M123-dev]

Looks good, can't really think of a better solution

[abhay1821]

Thank You for your review @M123-dev. So Actually had a discussion with monsieurtanuki. So we often find text-overflow problems with different phones sizes . And sometimes using FittedBox itself brings up its own repercussion. Using this package can fix all our overflow problems throughout the App ;)

@abhay1821 I agree with you, now that you've embedded auto_size_text, I guess we should definitely use it on other screens.

Perhaps we should play a bit with it, before spreading its use to the rest of the app:

• typical values for the font size (e.g. double.infinity?)
• typical max number of lines
• typical restriction (width or height?)

Looks like a good improvement anyway!
