tekle-eyesus/smartcrop_ai ? reverse-engineered prompt

Build me a Flutter mobile app called SmartCrop AI that helps farmers identify crop diseases from a photo of a leaf and gives them clear advice on what to do next. It should work offline for the main detection part, let the user take a picture or pick one from the gallery, and then show the likely disease, confidence, and simple next steps. Make it support tomato, potato, and mango, with helpful disease specific guidance, tips, and a clean results screen that can show charts or confidence levels. I also want an assistant where users can ask farming questions and get friendly, practical answers based on the detected issue. Include a place to save past detections so people can review them later, plus videos or rich text tips for learning more. Keep the app simple, easy to use, and good for smallholder farmers. If you need to check current docs for anything, look them up online.
