[hamzamirai]

This pull request updates the project to use the latest Flutter and Gradle versions, ensuring compatibility and resolving build issues on Android. The following changes have been made:

• Updated to Flutter 3.24.3 for improved performance and latest Flutter features.
• Upgraded the Gradle Wrapper to version 8.9 (gradle-8.9-all.zip) to support the latest tooling.
• Upgraded the Module version to 8.7.0 for better compatibility and dependency management.

These updates should improve overall stability, resolve Kotlin/Gradle issues, and ensure compatibility with the latest Flutter tooling.

Testing:

• Successfully built and tested the project on Android devices and emulators with no issues.
• Ensured that all unit and widget tests pass.
