 # zapstore

-A new Flutter project.
-
-## Getting Started
-
-This project is a starting point for a Flutter application.
-
-A few resources to get you started if this is your first Flutter project:
-
- [Lab: Write your first Flutter app](https://docs.flutter.dev/get-started/codelab)
- [Cookbook: Useful Flutter samples](https://docs.flutter.dev/cookbook)
-
-For help getting started with Flutter development, view the
-[online documentation](https://docs.flutter.dev/), which offers tutorials,
-samples, guidance on mobile development, and a full API reference.
+ - test on macos
+ - drop file
+   - compute sha256 and query nostr by `x`
+ - install button
+  - downloads file (to whwatever the downloads provider is)
+  - checks sha256 with crypto and updates statenotifier bool state
+  - display if matches (green) or not (red)
