How to use Usermetric to publish messages to welcome screen

We can post messages via the Usermetric API to our phone's welcome page (the phone's lock screen). In the lock screen, we can double-hit the circle, to cycle through our mobile phone posted messages. As shown,

We have released a message "Useermetric messages Received:4".

The modules we need to use are:

Import Usermetrics 0.1

We can get all of its APIs using the following method:

[email protected]:~$ qmlplugindump Import usermetrics 0.1qqmlcomponent:component is not ready[email  protected]:~$ qmlplugindump usermetrics 0.1import qtquick.tooling 1.1//This file describes the Plugin-supplied types con tained in the library.//It's used for QML tooling purposes only.////This file was auto-generated by://' Qmlplugindump U        Sermetrics 0.1 ' Module {Component {name: ' Metric ' prototype: ' Qobject ' exports: ["Metric 0.1"] Exportmetaobjectrevisions: [0] Property {name: ' name '; Type: ' String '} property {name: ' Format '; typ        E: "String"} property {name: "Emptyformat"; Type: ' String '} property {name: "Domain"; Type: "String"}            Property {name: ' Minimum '; Type: ' Double '} property {name: ' Maximum '; Type: ' Double '} Method { Name: "Increment" Parameter {name: "Amount"; Type: "Double"}} Method {name: "Incremen T "} Method {NamE: "Update" Parameter {name: "value"; Type: "Double"}}} 

Our application is very simple:

"); Incomingmessagesmetric.increment ( -2)}} Button {text:i18n.tr ("D                    Ecrease ") onclicked: {Console.log (" going to update to 3 to the metric! "); Incomingmessagesmetric.update (3)}}}}
