This beginner-friendly course introduces trainees to mobile application development using Dart and Flutter. It starts with programming fundamentals and environment setup, then progresses to building user interfaces, navigation, interactive features, state management, API integration, and local database connectivity.

Guided exercises and hands-on projects help trainees apply each topic as they develop a functional application. The course concludes with a capstone project that brings together the skills learned, including testing, debugging, and generating an installable Android APK.

The proposed duration provides beginners with time for guided practice, troubleshooting, and application development alongside the core lessons.
