Hi @fodedoumbouya, thank you for reporting. The crash means that we cannot create an UIImage from the given data that's fed from Flutter PointAnnotation. I have created an internal ticket https://mapbox.atlassian.net/browse/MAPSFLT-326 to track the progress, we will remove the force unwrapping in that line, meanwhile you can double check the way the image data correct when creating the point annotation.
