fromString static method

DiagnosticSeverity? fromString(String? value)

Parses a String into an DiagnosticSeverity instance.

• Returns null if the value is 'none' (case-insensitive), indicating that the severity should be treated as disabled.
• Returns the matching DiagnosticSeverity if a match is found, ignoring case.
• Returns null if the string does not match any known severity.

Implementation

static DiagnosticSeverity? fromString(String? value) {
  if (value?.toUpperCase() == DiagnosticSeverity.NONE.name.toUpperCase()) {
    return null;
  }

  return DiagnosticSeverity.values.firstWhereOrNull(
    (severity) => severity.name.toUpperCase() == value?.toUpperCase(),
  );
}
