Question - What are the Snapshots in Dart?
Answer -
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.
