Feature request: creating snapshots from isolates and spawning isolates from snapshots #20417

This issue was originally filed by @BigBen1307

As far as i know, it is currently not possible to create snapshots inside dart programmatically. It would be great to have the possibility to create snapshots from dart isolate instances. Whenever the same isolate is created with spawnUri, the snapshot could be used instead.

Possible implementation:

Uint8List cachedSnapshot;

if(cachedIsolate == null) {     Isolate.spawnUri(...).then(         (Isolate iso)         {             cachedSnapshot = iso.createSnapshot();         }     ); } else {     Isolate.spawnSnapshot(cachedSnapshot, ...); }

Added Area-VM, Triaged labels.

Personally I don't think this is a good idea. The file at the URI should already be a snapshot if necessary, but this is a library enhancement in the first place.

Removed Area-VM label. Added Area-Library, Library-Isolate labels.

If the file at the URI would already be a snapshot, how would I load it into my currently running script?

Reassigning to VM. The big chunk of work is VM specific.

The library team would be happy to help with the public facing APIs.
