FieldPath.fromString constructor

FieldPath.fromString(String path)

FieldPath.fromString(String path)
    : components = path.split('.'),
      assert(path.isNotEmpty),
      assert(!path.startsWith('.')),
      assert(!path.endsWith('.')),
      assert(!path.contains('..')),
      assert(!path.contains('~'), _reserved),
      assert(!path.contains('*'), _reserved),
      assert(!path.contains('/'), _reserved),
      assert(!path.contains('['), _reserved),
      assert(!path.contains(']'), _reserved);
