What is the purpose of the pubspec.yaml file in a Flutter project?

The pubspec.yaml file is used for managing dependencies, project metadata, and build configuration in a Flutter project.

Main sections:

• name: The project name.

• description: A brief description of the project.

• publish_to: Package publishing settings (none for private projects).

• version: The package version (application or library).

• environment: The minimum SDK version required for the project.

• dependencies: List of packages your project depends on. These are the main dependencies needed to run the code.

  dependencies:
    flutter:
      sdk: flutter
    cupertino_icons: ^1.0.2
    english_words: ^4.0.0
  

• dev_dependencies: Packages needed only during development, testing, and building, but not for running the final app.

  dev_dependencies:
    flutter_test:
      sdk: flutter
  
    flutter_lints: ^1.0.0
  

• flutter: Flutter-specific settings, such as defining used resources (assets), fonts, and platform integration.

  flutter:
    uses-material-design: true
  
    assets:
      - images/a_dot_burr.jpeg
      - images/lake.jpeg
  
    fonts:
      - family: Schyler
        fonts:
          - asset: fonts/Schyler-Regular.ttf
          - asset: fonts/Schyler-Italic.ttf
            style: italic
  

The flutter pub get command uses this file to download the specified dependencies.
