buildSnapshotPresentationKey function

String buildSnapshotPresentationKey(SnapshotOptions? options)

Build a stable string key from SnapshotOptions that identifies the presentation parameters. Two snapshots with the same key were captured with equivalent filtering and are directly comparable.

Implementation

String buildSnapshotPresentationKey(SnapshotOptions? options) {
  final interactiveOnly = options?.interactiveOnly == true;
  final compact = options?.compact == true;
  final depth = options?.depth;
  final scope = (options?.scope ?? '').trim();
  final raw = options?.raw == true;
  // Build a deterministic JSON-like string without needing dart:convert.
  return '{"interactiveOnly":$interactiveOnly,"compact":$compact'
      ',"depth":${depth ?? 'null'}'
      ',"scope":${scope.isEmpty ? 'null' : '"$scope"'}'
      ',"raw":$raw}';
}
