getLevel method

int getLevel()

Returns the indentation level of _input.

An indentation level is determined by finding a non-empty line with the least amount of leading whitespace.

For example, with input:

Hello World

the indentation level is 1, because the line with " World" has the least amount of leading whitespace.

Implementation

int getLevel() {
  final lines = _processLines();
  return _findCommonIndentationLevel(lines);
}
