Flutter md link not loading md file - flutter

Question

I am using the flutter_markdown widget to display help info in my app.
Inside an md file I am using the link to another md file. Both md files are defined in the 'assets' list in the pubspec.yml file
### [Overview](resource:asset/doc/overview.md) / Match Screen ###
Then I'm using the 'onTapLink' event handler to capture the users tap on the link to reset the markup widget to display the new md file like...
Future<String> _getData(String aFileName) async{
return rootBundle.loadString(aFileName);
}
#override
Widget build(BuildContext context) {
// get
return Scaffold(
appBar: AppBar(title: Text('Help')),
body: FutureBuilder<String>(
future: _dataFuture,
builder: (BuildContext context, AsyncSnapshot<String> snapshot) {
if (snapshot.hasData) {
return Markdown(data: snapshot.data!, onTapLink: (text,href,title) {
setState(() {
_dataFuture = _getData(href!);
});
},);
}
return Center(
child: CircularProgressIndicator(),
);
}),
);
}
However, the onTapLnk code is causing an exception where it can't load the md file name passed in 'hef'
E/flutter ( 7261): [ERROR:flutter/lib/ui/ui_dart_state.cc(209)] Unhandled Exception: Unable to load asset: resource:asset/doc/overview.md
E/flutter ( 7261): #0 PlatformAssetBundle.load (package:flutter/src/services/asset_bundle.dart:237:7)

E/flutter ( 7261): <asynchronous suspension>
E/flutter ( 7261):
Any suggestions?
Through testing I can separately display both md files, so its nothing to do with faulty asset definition in the pubspec.yml file.

Solved it
The link definition in the md file should be
### [Overview](asset/doc/overview.md) / Match Screen ###
not
### [Overview](resource:asset/doc/overview.md) / Match Screen ###
