What is pubspec.

Pubspec is a file used in Dart programming language to define the metadata and dependencies for a Dart project. It is a YAML file named pubspec.yaml that is placed in the root directory of a Dart project.

In the pubspec file, you can define information such as the name and version of the project, its description, author, homepage, and license. Additionally, you can specify the dependencies for your project, which are the packages that your project requires to run.

Pubspec also allows you to specify other details about your project, such as the environment configuration, the entry point of the application, and assets like images, fonts, and other files.

The pubspec file is used by the pub package manager to manage the dependencies of your project and ensure that they are installed correctly. When you run the “pub get” command, the package manager reads the pubspec file and downloads the specified packages and their dependencies from the pub.dev repository or other sources.
