LateInitializationError: Local 'result' has not been initialized.

In version 0.14.0 I get this error when calling the generate() method:

Unhandled exception:
LateInitializationError: Local 'result' has not been initialized.
#0      LateError._throwLocalNotInitialized (dart:_internal-patch/internal_patch.dart:214:5)

The problem seems to be in the toDartType method in schema.dart: if unions.entries is empty then result will never be assigned:

        if (anyOf != null && unions != null) {
          final subSchemas = anyOf.map((e) => e.toDartType()).toList();
          final leq = ListEquality();
          for (final e in unions.entries) {
            if (leq.equals(subSchemas, e.value)) {
              final type = e.key.pascalCase;
              if (nullable == true) {
                result = '$type?';
              } else {
                result = type;
              }
            }
          }
          break;

Changing the top if statement to this made it work:

        if (anyOf != null && unions != null && unions.isNotEmpty) {

Perhaps there needs to be a similar change for anyOf?
