@limsocheat could you provide an example which can be copy pasted and tested this one is not runnable

[vasilich6107]

This is the errors that I see when copy paste into example project for reproduction

[chrisvidal]

same issue with flutter_awesome_select: ^6.1.2-beta and S2Chips used in S2Tile.fromState(

somehow with the beta version, state.selected.choice is null

[vasilich6107]

@chrisvidal Could you provide working reproduction code?

[chrisvidal]

sorry I don't have time to create a specific code for this :( It was working fine before updating to the flutter_awesome_select: ^6.1.2-beta

my code is directly inherited from the examples actually with single choice with modal sheet selection

[vasilich6107]

Closing issue due to the missing reproduction Feel free to reopen with runnable reproduction code
