Feature Request : Filter functionality in our beacons

**Is your feature request related to a problem? Please describe.**
Suppose in crew of several members different people are able to create a beacon. It will become a tedious task to look upon every beacon to search a particular beacon.

**Describe the solution you'd like**
Here the filter functionality can play a vital role to optimize searching based on the person who had created a beacon. Currently in every beacon card has beacon name and who had made it as **"Beacon Name by Creator Name"** So at the time when we take information from backend about every beacon and display it on cards we will store the owner names in a set and use these names to provide filter functionality.

**Describe alternatives you've considered**
Alternative to this can be to implement search bar where user can search a particular beacon name. But in this case we need to know perfect name of beacon otherwise we'll end up no result found.

**Additional context**
1. Use of Icon Button (with provided button color in theme as yellow).
2. Use of pop-up menu by onTap on icon button.
3. Showing the list of all beacon owners of whom we have joined the beacons from earlier(like as if we have registered it).

**Are you working on this? (Yes/No)**
Yes
