Can't using the latest version of http in the project

[Achuabhijith2003]

"The current Dart SDK version is 3.4.3.

Because google_fonts >=4.0.5 depends on http ^1.0.0 and pdf_text >=0.5.0 depends on http ^0.13.0, google_fonts >=4.0.5
is incompatible with pdf_text >=0.5.0.
And because pdf_text <0.5.0 doesn't support null safety, google_fonts >=4.0.5 is incompatible with pdf_text.
So, because [Projectname] depends on both google_fonts ^6.2.1 and pdf_text any, version solving failed."

The lower bound of "sdk: '>=2.1.0 <3.0.0'" must be 2.12.0 or higher to enable null safety.

Can't using the latest version of http if downgrade gernerative_ai package not support it require http 1.1.0

"Because google_generative_ai 0.4.4 depends on http ^1.1.0 and no versions of google_generative_ai match >0.4.4 <0.5.0, google_generative_ai ^0.4.4 requires http ^1.1.0."

and problem in null safety isssues
