How to Run Projects

1. Clone the repository:

git clone https://github.com/KunalNepali/flutter_dart.git
cd flutter_dart

2. 
    Navigate to the project folder you want to run. For example:

cd todo_app

    Get dependencies:

flutter pub get

    Run the app:

flutter run

    Repeat steps 2–4 for other projects (bmi_calculator, expense_tracker, etc.)
