decodedSnapshotFor method

@override Image decodedSnapshotFor(SnapshotSource source)

The pre-decoded image for snapshot source — synchronous by contract, so paint hands it straight to a RawImage with no async-in-frame.

Only valid after preResolveSnapshots completed for source; implementations throw on an unresolved source instead of a blank frame.

Implementation

@override
ui.Image decodedSnapshotFor(SnapshotSource source) => throw FluvieRenderException(
  'NoMediaResolver has no decoded snapshot for "$source". Wire a '
  'MediaRepository through mediaResolverProvider to render snapshots.',
);
