How to get the detailed API interface for the QML package

Although our developer website has a rich API introduction, some API introductions may not be complete, and some APIs are constantly evolving. In order to get a more detailed API, we can get more detailed information through the following commands. For example, we get more information about the "Singledownload" API.

$qmlplugindump Ubuntu.downloadmanager 0.1

The results shown are as follows:

Import Qtquick.tooling 1.1
