VistasFirebase adding data into an array
I would like to add a new product to the allProducts array without deleting the existing product.
Here is the database.
And the code. This solution always overwrite the existing product.

If you want to add an item to an existing array, you can:
- Either load the document, get the existing array from that, add the item to it, and then write the entire array back to the database.
- Or you can use the
array-unionoperator that is described in the documentation on updating an item in an array.
You'll probably want to do the latter here.
