I am trying to install Flutter package "image_picker". When I run flutter pub add image_picker
I get the following error:
The current Dart SDK version is 3.0.1.
Because image_picker <0.7.0-nullsafety doesn't support null safety and image_picker >=0.8.4 <0.8.6 depends
on image_picker_platform_interface ^2.3.0, image_picker <0.7.0-nullsafety or >=0.8.4 <0.8.6-∞ requires
image_picker_platform_interface ^2.3.0.
And because image_picker >=0.8.2 <0.8.4 depends on image_picker_platform_interface ^2.2.0, image_picker
<0.7.0-nullsafety or >=0.8.2 <0.8.6-∞ requires image_picker_platform_interface ^2.2.0.
And because image_picker >=0.8.1 <0.8.2 depends on image_picker_platform_interface ^2.1.0 and image_picker
>=0.7.0 <0.8.1 depends on image_picker_platform_interface ^2.0.0, image_picker <0.7.0-nullsafety or >=0.7.0 <0.8.6-∞ requires image_picker_platform_interface ^2.0.0.
Because image_picker_platform_interface >=2.0.0-nullsafety <2.0.0 depends on http ^0.13.0-nullsafety.0 and
image_picker >=0.7.0-nullsafety <0.7.0 depends on image_picker_platform_interface ^2.0.0-nullsafety,
image_picker >=0.7.0-nullsafety <0.7.0 requires http ^0.13.0-nullsafety.0 or
image_picker_platform_interface ^2.0.0.
Thus, image_picker <0.8.6 requires http ^0.13.0-nullsafety.0 or image_picker_platform_interface ^2.0.0.
And because image_picker >=0.8.6 depends on image_picker_platform_interface ^2.6.1, every version of
image_picker requires http ^0.13.0-nullsafety.0 or image_picker_platform_interface ^2.0.0.
And because image_picker_platform_interface >=2.0.0 depends on http ^0.13.0 and google_fonts >=4.0.5
depends on http ^1.0.0, google_fonts >=4.0.5 is incompatible with image_picker.
So, because favorite_places_app depends on both google_fonts ^4.0.5 and image_picker any, version solving
failed.
The lower bound of "sdk: '>=1.8.0 <2.0.0 or >=2.0.0-dev.28.0 <3.0.0'" must be 2.12.0 or higher to enable null safety.
For details, see https://dart.dev/null-safety
I also tried installing the package by inserting the name under dependencies in pubspec.yaml, but same result.

You need to update your pubspec.yaml file to enable null safety feature. Go to pubspec.yaml file and change sdk version under environment
adjust your http or google_fonts dependency versions in ‘pubpec.yaml’ file.
ex> http: ^1.0.1 => ^0.13.0
