When you try to launch the component via app , standard events (toast, navigateToSobject, etc) will be undefined.

Refer below link for similar discussion.

Hi venkat,

When you try to launch the component via app (demoApp in your case) , standard events (toast,  navigateToSobject,  etc)  will be undefined.
        var toastEvent = $A.get("e.force:showToast");
        toastEvent will have "undefined " always.

Therefore launch your toastComponent in LEX via app builder or lightning quickaction or drag to detail page to check how it works.

Otherwise you will try this code for Show Toast:
<aura:attribute name="notificationmessage" type="String"/>
<aura:handler action="{!c.doinit}" value="{!this}" name="init"/>
<div class="slds-modal slds-fade-in-open errorDiv slds-hide" aura:id="warningDiv">
        <ui:inputText aura:id="articleURL"/>
        <div class="demo-only" style="height: 8rem;">
            <div class="slds-notify_container slds-is-relative">
                <div class="slds-notify slds-notify_toast slds-theme_success" role="alert">
                    <div class=" slds-m-left_xx-large">
                        <div class="slds-notify__content slds-m-left_small slds-align_absolute-center slds-m-left_xx-large">
                            <lightning:icon alternativeText="Success" iconName="utility:success" size="small"
                                            class="buttonColor slds-m-right_small" />
                            <h2 class="slds-text-heading_small ">{!v.notificationmessage}</h2>
    doinit : function(c, e, h) {

        c.set("v.notificationmessage", 'This is example of display toast.');
                              $A.util.removeClass(c.find('warningDiv'), 'slds-hide');
                               window.setTimeout($A.getCallback(function() {
                               $A.util.addClass(c.find('warningDiv'), 'slds-hide');
                                  }), 3000);
I hope you find the above solution helpful. If it does, please mark as Best Answer to help others too.
