Unable to run project in android studio

[PrinceTayal]

I have searched all stackoverflow and github and applied the solutions for this problem but nothing seems to work.

When I run flutter pub get it throws an error show in image below

I have tried updating the sdk version in pubsec.yaml to min of 2.12.0 but it doesn't seem to work.
Would be great if somebody can help

PFA pubsec.yaml

The following line ensures that the Material Icons font is

included with your application, so that you can use the icons in

the material Icons class.

uses-material-design: true
