    Learning Objectives

    • Understand what Flutter is and how it differs from web/native tools
    • Explore Flutter's rendering architecture (Impeller and Skia engines)
    • Understand the AOT (Ahead-of-Time) and JIT (Just-in-Time) compilation workflows
    • Learn why Google chose Dart as Flutter's programming language

    What You'll Learn

    1. What is Flutter and why developers choose it
    2. Comparing multi-platform approaches: WebViews vs Bridges vs Native Compile
    3. Understanding widget tree rendering mechanics
    4. The role of the Dart VM in hot reload and production builds

    Key Concepts

    Flutter
    Dart
    SDK
    Rendering
    Hot Reload
    Native Compilation

    Key Takeaways

    • Flutter compiles Dart code directly to native ARM and Intel instructions for optimal performance.
    • By drawing its own UI pixel-by-pixel using Impeller/Skia, Flutter bypasses slow native host system web containers.
    • Hot Reload injects code edits straight into the Dart VM without losing active app state, speeding up design.
