how to set value to if the path path does not exist

[maxzod]

iam working on CLI features that see the content of the assets directory and add pathes to pubspec.yaml based on that it works with update if there is already a list in pubspec assets

    final doc = YamlEditor(pubspecContent);
    doc.update(['flutter','assets'], assets);

BUT if there is no assets key n the pubspec under flutter

flutter:
  uses-material-design: true

it throws exception

i think this is the expected behavior to throw when updating a null but how could i set value to a key that does not exist+

@maxzod, you should be able to insert a new key in a YamlMap using YamlEditor.

Can you make provide a complete minimal example of this issue?

I have no issues doing:

import 'package:yaml_edit/yaml_edit.dart';

void main() {
  final yamlEditor = YamlEditor('''
flutter:
  uses-material-design: true
''');
  yamlEditor.update([
    'flutter',
    'assets'
  ], {
    'foo': 'foo.jpg',
    'bar': 'bar.png',
  });
  print(yamlEditor.toString());
}

that prints:

flutter:
  assets:
    foo: foo.jpg
    bar: bar.png
  uses-material-design: true
