[google_sign_in] GoogleUserCircleAvatar throws "Invalid image data" #88329
Description
Steps to Reproduce
GoogleUserCircleAvatar throws "Invalid Image Data" because of this line:
placeholder: Uint8List((size.round() * size.round())),This generates an empty array with 0 (which is NOT a valid image).
Changing the above line to
placeholder: base64Decode("R0lGODlhAQABAIAAAP///wAAACH5BAEAAAAALAAAAAABAAEAAAICRAEAOw=="),fixes the problem (this is an transparent 1x1 gif image as base-64).
