How to put a photo frame images in firebase and then select a photo in which we want to overlay.

[Manish Thapa]

I want to develop an application which takes a photo and then the user selects the frame and adjusts/crops the photo. The photos frames are to be uploaded manually to firebase and called in app using the Api. Lastly thr user saves the photo to the device and firebase. I dont know where to start at, what concepts or samples should I look at. I did a lot of research but couldnt find. Please help me by recommending the things I should follow and look at. Thanks in advance.
