generateAll method

@override Future<void> generateAll(Iterable<GenerativeSource> sources, { void onProgress(GenerativeProgress progress)?, })

Produces every source in sources (cache hit or generate) so that mediaFor, audioFor, and metaFor can answer synchronously afterwards.

Runs before the first frame and is idempotent: producing the same source (by GenerativeSource.cacheKey) twice does the work once. Reports coarse progress through onProgress. Throws a FluvieGenerativeException when a source cannot be produced (provider error, offline cache miss, or budget).

Implementation

@override
Future<void> generateAll(
  Iterable<GenerativeSource> sources, {
  void Function(GenerativeProgress progress)? onProgress,
}) async {
  if (sources.isNotEmpty) {
    throw FluvieGenerativeException(
      'No generative backend is installed (got ${sources.length} source(s), '
      'first: "${sources.first}"). $_install',
    );
  }
}
