onResourceContentUpdated method
Register a handler for notifications/resources/updated that carries
the new content: the handler gets the resource's URI and its contents.
A notification without content (the usual case) does not reach it — use
onResourceUpdated for those.
Implementation
void onResourceContentUpdated(
Function(String uri, ResourceContents content) handler,
) {
onNotification(McpProtocol.methodResourceUpdated, (params) {
final uri = params['uri'] as String;
final contentData = params['content'];
if (contentData is! Map) return;
handler(uri, ResourceContents.fromJson(Map<String, Object?>.from(contentData)));
});
}
