audio_stream 4.3.0 and noise_meter 5.1.0

[iarata]

A fix #1242 to prevent multiple threads from being created when starting a new recording session in audio_stream, along with updates to Gradle, Kotlin, and minimum supported SDK and iOS versions. The Android and iOS example projects have also been updated to match these changes.

Bug Fixes and Audio Streaming Improvements

Dependency and Platform Upgrades

• Updated Gradle and Kotlin versions in both the plugin and example projects for improved compatibility and build performance (build.gradle, settings.gradle, gradle-wrapper.properties). [1] [2] [3] [4]
• Bumped minimum Dart SDK to >=3.8.1 and updated permission_handler dependency to ^12.0.0.

iOS Platform Support

• Increased minimum iOS deployment target from 12.0 to 13.0 across all relevant files and updated the Podfile accordingly. [1] [2] [3] [4] [5] [6] [7] [8]
• Updated Xcode project configuration to use file lists for input/output paths and added support for custom LLDB init files. [1] [2] [3] [4]

Miscellaneous

• Removed deprecated or unnecessary Android Gradle properties in both plugin and example projects. [1] [2]
