void renderSnapshotPreview(LiveBlock block, String device, LiveSnapshot snapshot, { String export = 'export', })

Adds the storage and Backpack tables of snapshot from device to block, ending with how to save it with export.

Implementation

void renderSnapshotPreview(
  LiveBlock block,
  String device,
  LiveSnapshot snapshot, {
  String export = 'export',
}) {
  List<List<String>> rows(Map<String, Object?> values) => [
    for (final MapEntry<String, Object?> entry in values.entries)
      [
        entry.key,
        LiveSnapshot.describeEntry(entry.value).type,
        LiveFormat.value(LiveSnapshot.describeEntry(entry.value).value),
      ],
  ];

  block.heading(
    'Storage on $device (${snapshot.storage.length} '
    '${snapshot.storage.length == 1 ? 'value' : 'values'}, '
    '${_describeSize(snapshot.sizeInBytes)})',
  );
  if (snapshot.storage.isEmpty) {
    block.note('Storage is empty');
  } else {
    block.table(['KEY', 'TYPE', 'VALUE'], rows(snapshot.storage));
  }
  block.plain('');
  block.heading(
    'Backpack (${snapshot.backpack.length} '
    '${snapshot.backpack.length == 1 ? 'value' : 'values'})',
  );
  if (snapshot.backpack.isEmpty) {
    block.note('Backpack is empty');
  } else {
    block.table(['KEY', 'TYPE', 'VALUE'], rows(snapshot.backpack));
  }
  renderSnapshotWarnings(block, snapshot);
  block.note(
    'Save it as a seeder with $export <name>, or as a file with '
    '$export --to <path>.json',
  );
}
