[cj3479]

Description The Sentry flutter version is 6.22.0

Should this go to the https://github.com/getsentry/sentry-dart repo? This seems like an SDK issue rather than something to do with issues.

[arc-yong]

@toannmdev this might be related to this fix https://github.com/getsentry/sentry-java/pull/3200

try to upgrade to our flutter sdk >= 7.17.0 and see if this problem remains
