Should I file a bug report for this one

jim · Answer

Looks like that API was changed a week ish ago <https android review googlesource com c platform frameworks support + 1544024 12 compose ui ui text src commonMain kotlin androidx compose ui text input TextFieldValue kt b47|https android review googlesource com c platform frameworks support + 1544024 12 compose u tlin androidx compose ui text input TextFieldValue kt> how old is your snapshot

Kshitij Patil · Answer

Okay so this issue occurs in the snapshot I mentioned Has it fixed in any latest one

jim · Answer

Looks like the snapshot you mentioned 7094152 which was built approximately 2021 01 20 but the CL was merged approximately 2021 01 15 so I suppose that CL broke that snapshot Yes please file a bug and include a repro Looks like the problem is not directly related to TextFieldValue which accepts an AnnotatedString in your build but is instead somehow related to `savedInstanceState` cc < Siyamed>

Hi < Kshitij Patil> I cannot reproduce the exception unfortunately I suspect of a line but I cannot understand the use case or how this happened and without the repro I am afraid I wont be able to properly fix this

Pass String to `TextFieldValue` put app in background and bring back to foreground it ll crash
