What are the Snapshots in Dart?
The Dart relies heavily on snapshots. Snapshots are files that include objects and other runtime information.
Script snapshots : Snapshot files can be created from Dart programs. All of the program code and dependencies are prepared and ready to run in these folders. This enables quick start-ups.
Full snapshots : The Dart core libraries can be compiled into a snapshot file, allowing them to be loaded quickly. The core libraries are prebuilt snapshots that are loaded at runtime in most standard distributions of the main Dart.
Object snapshots : Dart is an asynchronous programming language. For concurrency, it takes advantage of isolates. Because these are message-passing workers, a mechanism to serialize a message is required. This is accomplished by creating a snapshot from a particular object, which is then passed to another isolate for deserialization.
