How to dismiss LoadingController once method is executed in Ionic Angular app?

@Sweg wrote:

In my Ionic Angular app, I am creating a LoadingController in the below method:

Conversation-detail.page.ts:

onSendMessage() {
    this.loadingCtrl.create({
      message: 'Sending Message...'
    }).then(loadingEl => {
      loadingEl.present();
      this.conversationsService.addMessageToConversation(this.conversation.id, this.form.value.message);
    })
}

Once the LoadingController is presented, I want to execute this.conversationsService.addMessageToConversation(...)

Then once that method is executed successfully, I want to execute loadingEl.dismiss(), but I don’t know where to call this. It should only be dismissed if addMessageToConversation(...) is executed.

Can someone please tell me how I can resolve this?

Also, here is some of my other code (can provide more if required:

Conversations.service.ts:

addMessageToConversation(conversationId: string, message: string) {
    this.getConversationToAddMessage(conversationId).messages.push(this.createMessage(message));
  }

getConversationToAddMessage(id: string) {
    return this._conversations.getValue().find(conversation => conversation.id === id);
  }
