In Flutter, what is the purpose of the pubspec.lock file?
- Indicating the project's build configurations
- Locking down the exact versions of dependencies
- Specifying the minimum version of Flutter required
- Storing metadata about the project's dependencies
The 'pubspec.lock' file in Flutter serves the purpose of storing metadata about the project's dependencies. It locks down the exact versions of each package used in the project, ensuring that everyone working on the project uses the same versions of dependencies. This helps maintain consistency and avoids compatibility issues that might arise due to different versions. Developers should not manually modify the 'pubspec.lock' file; it is automatically generated and managed by Flutter.
