string static method

String? string(
  1. String? value
)

Returns a string from the specified string.

Returns the empty string if it's not a string.

This is useful in situations where null is not acceptable, for example, when providing a decoder to list. Otherwise, prefer using DataSource.v directly.

Implementation

static String? string(String? value) {
  if (value == null) return null;
  return '\'$value\'';
}
