The lower bound of "sdk: '>=2.7.0 .0.0'" must be 2.12.0 or higher to enable null safety.

Resolving dependencies... (1.6s)
The current Dart SDK version is 3.0.6.

Because universal_ui 0.0.8 doesn't support null safety and no versions of universal_ui match >0.0.8 <0.1.0, universal_ui ^0.0.8 is forbidden.
So, because emarket_user depends on universal_ui ^0.0.8, version solving failed.

The lower bound of "sdk: '>=2.7.0 .0.0'" must be 2.12.0 or higher to enable null safety.
