    Learning Objectives

    • Incorporate scrollable lists using standard ListView controllers
    • Improve rendering efficiency of large lists using ListView.builder
    • Display item matrices using GridView constructors and grid delegates
    • Customize scrolling feedback using ScrollPhysics settings

    What You'll Learn

    1. Static lists vs dynamic resource-efficient builder layouts
    2. Using ListView.builder lazy generation to render offscreen elements on-demand
    3. Creating grids: GridView.count and GridView.builder implementations
    4. Structuring lists with built-in ListTile patterns

    Key Concepts

    ListView
    ListView.builder
    GridView
    ListTile
    ScrollPhysics
    Lazy Rendering

    Key Takeaways

    • ListView.builder dynamically allocates items visible in the viewport, saving memory.
    • GridView maps lists to customizable grid matrices using grid delegate managers.
    • ListTile provides standard slot alignments for icons, titles, descriptions, and action elements.
