Release Notes

Version 1.1.7 (21 May 2025)

1. Fixes Github Issue #144 - Up to version 1.1.6, the setFlushPolicies method inadvertently overwrote the Configuration.collectDeviceIdproperty. This issue has been resolved in version 1.1.7.

2. Fixes Github Issue #147 - The compileSdkVersion in the build.gradle file has been updated from 31 to 35. Previously, this caused the following error:
   Android build error "Only safe (?.) or non-null asserted (!!.) calls are allowed on a nullable receiver of type 'android.content.pm.ApplicationInfo?" . This update resolves the issue with compileSdkVersion 35.

3. Fixes Github Issue #138 - Prior to version 1.1.7, the version field returned the browser's version string instead of the app version from pubspec.yaml. Since pubspec.yaml is a build-time configuration file and not accessible at runtime (especially in browser environments), this was expected behavior.
   As of version 1.1.7, if the following tag is added to <project-root>/web/index.html: <meta name="app-version" content="1.2.3">
   the app will return the value in the content attribute.
   Note: This value should be manually synchronized with the version in pubspec.yaml.

4. Fixes Github Issue #152 and #98 - Until version 1.1.6, the integrations: {} field was missing in the data payload sent to the Segment server. This has been addressed in version 1.1.7.

5. Fixes Github Issue #157 - Resolves the Concurrent modification during iteration: Instance(length: 6) of '_GrowableList' error that occurred when multiple plugins were added simultaneously.
