这个error是在点击时触发的还是渲染的时候？

[wudb]

点击的时候

[minhtritc97]

same issue

[TinoGuo]

it seems there is breaking change in recent flutter release, it works in 3.10.5.
to mitigate the issue, pls keep old version, I will try to fix it in next release

[TinoGuo]

from https://github.com/flutter/flutter/issues/150638, it seems this PR https://github.com/flutter/flutter/pull/143954 break the implementation and make it doesn't work, will leave flutter team to fix it.

[kapibara91]

it also works on 3.22.3

[TinoGuo]

fixed in 4.5.2, test with latest flutter version and working fine, thx @dejunDev
