      Find the end of the class/func block starting at `start_index` in a source code (defined by `lines`).
  
      Args:
          lines (`List[str]`):
              The source code, represented by a list of lines.
          start_index (`int`):
              The starting index of the target class/func block.
          indent (`int`):
              The indent of the class/func body.
  
      Returns:
          `int`: The index of the block's ending line plus by 1 (i.e. exclusive).
