no way to add a key in a blank yaml file #32

Closed animeshjain closed 1 year ago

Example: 

final doc = YamlEditor('');
doc.update(['bar'], 'val2');
print(doc);

fails with Invalid path: [bar]. Scalar null does not have key bar

whereas..

final doc = YamlEditor('foo: val1');
doc.update(['bar'], 'val2');
print(doc);

works fine

I think you need to add an object, when the root object is null.
