readFileBytes method

Uint8List readFileBytes(String subPath)

Reads the (inflated) bytes of a file member. Throws when the member is missing, a directory, or exceeds maxArchiveMemberBytes declared.

Implementation

Uint8List readFileBytes(String subPath) {
  final normalizedPath = normalizeArchiveLookupPath(subPath);
  if (normalizedPath == null) {
    throw StateError("Archive path cannot contain '..'");
  }
  final entry = _entries[normalizedPath];
  if (entry == null) {
    throw StateError("Archive path '$normalizedPath' not found");
  }
  if (entry.isDirectory) {
    throw StateError("Archive path '$normalizedPath' is a directory");
  }
  if (entry.size > maxArchiveMemberBytes) {
    throw StateError(
      "Archive entry '$normalizedPath' is too large to read "
      '(${entry.size} bytes > $maxArchiveMemberBytes byte limit)',
    );
  }
  final content = entry.file!.content;
  return content;
}
