It looks like you're using the

$gte

operator to gate users based on app version (e.g.,

"mobileAppVersion": { "$gte": "1.18.1" }"

). However, the

$gte

operator in

growthbook_sdk_flutter

performs numeric comparisons only using

double.tryParse(...)

. Since version strings like

"1.18.1"

cannot be parsed as valid numbers, the condition fails to evaluate correctly and instead returns the default result - true. This can unintentionally include all users in the experiment, regardless of their actual app version. To properly compare semantic version strings (e.g.,

"1.18.1"

), you should use the

$vgte

operator, which compares each version component correctly (

major.minor.patch

). To fix this, go to the Advanced Settings of your targeting condition and use the following format:

json
{
  "mobileAppVersion": { "$vgte": "1.18.1" }
}
