Facing the issue in pubspec.yaml - flutter

Question

When i integrate the library new_version: ^0.2.0 in the project after pub get i get this error -
Because new_version >=0.0.7 depends on package_info_plus ^1.0.0 which depends on package_info_plus_platform_interface ^1.0.0, new_version >=0.0.7 requires package_info_plus_platform_interface ^1.0.0.
And because package_info_plus_platform_interface >=1.0.0-nullsafety.1 depends on plugin_platform_interface ^2.0.0 and file_picker 2.1.6 depends on plugin_platform_interface ^1.0.1, new_version >=0.0.7 is incompatible with file_picker 2.1.6.
So, because fstore depends on both file_picker 2.1.6 and new_version ^0.2.0, version solving failed.
pub get failed (1; So, because fstore depends on both file_picker 2.1.6 and new_version ^0.2.0, version solving failed.)
I don't understand what does it mean is this flutter version issue or sdk issue???
Here is the pubspec.yaml file where all the library has been integrate for the project, if i remove the new_version library project will work perfectly fine.
name: fstore
publish_to: "none"

# The following defines the version and build number for your application.
# A version number is three numbers separated by dots, like 1.2.43
# followed by an optional build number separated by a +.
# Both the version and the builder number may be overridden in flutter
# build by specifying --build-name and --build-number, respectively.
# In Android, build-name is used as versionName while build-number used as versionCode.
# Read more about Android versioning at https://developer.android.com/studio/publish/versioning
# In iOS, build-name is used as CFBundleShortVersionString while build-number used as CFBundleVersion.

Answer 1

You can do sth like this to force using a specific version
dependency_overrides:
package_info_plus_platform_interface: ^1.0.0
or
dependency_overrides:
plugin_platform_interface: ^2.0.0

Answer 2

Just write new_version: any, and get the pub. After that, get the suitable version from pubspec.lock. You will get the solusion.
