Because no versions of pluto_grid match >5.4.9 <6.0.0 and pluto_grid 5.4.9 depends on intl ^0.17.0, pluto_grid ^5.4.9 requires intl ^0.17.0.
And because every version of flutter_localizations from sdk depends on intl 0.18.0, pluto_grid ^5.4.9 is incompatible with flutter_localizations from sdk.
And because flutter_date_pickers 0.4.2 depends on flutter_localizations from sdk and no versions of flutter_date_pickers match >0.4.2 <0.5.0, pluto_grid ^5.4.9 is incompatible with flutter_date_pickers ^0.4.2.
So, because extraaedge_v5 depends on both pluto_grid ^5.4.9 and flutter_date_pickers ^0.4.2, version solving failed.
