The key configuration file used when building a Flutter project is pubspec.yaml
.
This file contains metadata about your Flutter project, including:
- Project name: This is the name of your Flutter project and is used to identify it in the Flutter ecosystem.
- Dependencies: This section lists all the external packages your project depends on. It defines the package name, version, and any other relevant information.
- Flutter SDK version: This specifies the version of the Flutter SDK your project uses.
- Assets: This section lists all the assets used in your project, such as images, fonts, and other static resources.
- Environment variables: This section defines environment-specific configurations for your project, such as API keys or database connection strings.
The pubspec.yaml
file is essential for building, running, and deploying your Flutter project. It acts as a central hub for all project-related information and configurations.
Here's an example of a simple pubspec.yaml
file:
name: my_flutter_app
description: A new Flutter project.
publish_to: 'none'
version: 1.0.0+1
environment:
sdk: '>=2.12.0 <3.0.0'
dependencies:
flutter:
sdk: flutter
cupertino_icons: ^1.0.2
dev_dependencies:
flutter_test:
sdk: flutter
flutter_lints: ^2.0.0
flutter:
uses-material-design: true
This example shows the basic structure of a pubspec.yaml
file. You can add or modify sections based on your project's specific requirements.
