You can use the Icon or the logo.
The logo will be inside the app(top left), note: the logo comes as it is no corner padding.
The Icon will be on the loading screen + note: the app icon. And it has a corner padding.
Well, I think ratio is more important than pixel size. Generally square is common along with a few standard ratios depending on where they are displayed. I don’t really have a definitive guide on what size a logo should be.
Can you share a screenshot of what’s happening so we can better understand? What type of image is it? Does it have any transparent parts to it?
Here’s the transformation Glide is doing based on the URL I tested, using Cloudinary:
• Cloudinary fetches the image from Firebase.
• It resizes and crops the image to 300x300 pixels using the specified mode.
• It serves the image in the optimal format for the user’s browser.
I don’t think I ever have this problem, I think 1:1 should work just fine. If you can share the image, we’ll be happy to assist.
