level property Null safety
override
Priority level of the diagnostic used to control which diagnostics should be shown and filtered.
If ifEmpty is null and the value contains no non-null entries, then level DiagnosticLevel.hidden is returned.
Implementation
@override
DiagnosticLevel get level {
if (!_hasNonNullEntry() && ifEmpty == null) {
return DiagnosticLevel.hidden;
}
return super.level;
}
