If custom parser implementations required, please also import buffer_parser.dart
```
import 'package:oghref_model/buffer_parser.dart';
```

MetaFetch only recognize the first property name prefix in a sequence of <meta> tag in <head>. For example, given a HTML file:
```
<head>
    <meta property="og:title" content="Title"/>
    <meta property="twitter:card" content="summary"/>
</head>
```
In this case, MetaFetch only recognize og prefix and remaining metadata will be ignored. If preferred to override the first property prefix recognization, please apply this setting in MetaFetch (in this case, Twitter Card):
```
MetaFetch()..primaryPrefix = "twitter";
```
Unless for testing, URL response's content type must be satisified below:
- text/html
- application/xhtml+xml
Otherwise, MetaFetch refuses to parse properties to MetaInfo.
<meta> must be hard-coded in HTML, generated by JavaScript will be ignored.
