Because no versions of flutter_launcher_icons match >0.9.0 <0.10.0 and flutter_launcher_icons 0.9.0 depends on yaml ^3.0.0-nullsafety.0, flutter_launcher_icons ^0.9.0 requires yaml ^3.0.0-nullsafety.0.
And because every version of screenshots depends on yaml ^2.1.15, flutter_launcher_icons ^0.9.0 is incompatible with screenshots.
So, because e_sop depends on both screenshots ^2.1.1 and flutter_launcher_icons ^0.9.0, version solving failed.
