Setting Firebase data to property in html file
1
Okay so i am fairly new at ionic and i am experiencing this problem where by i am getting the users data from firebase but whenever i set it to the public variable and try and reference it in the html file, i am getting a log error of "cannot set 'variable name' to property of undefined". Here is my code for a more clearer explanation and understanding of what i am trying to achieve. Thank you.
.ts file:
import { Component } from '@angular/core';

Okay so i have tried basically everything and have decided to rather just upload the name to the database and write it locally in the storage of the application. I will just pull the name, along with further details later on in the application process. However if anyone finds an answer for this post, i would greatly appreciate it!
