Congratulations! You've completed the contest task. Users can create static stickers, remove the background, and use various editing tools. The submission provides a user-friendly design, with excellent stability and usability. 

The overall flow of creating a sticker set is very easy and intuitive. To further develop this app, we suggest implementing options to edit existing stickers and assign multiple emoji per sticker.

There's actually two small problems, but I don't think they're big enough to warrant individual issues, so I'm just listing them here:
1. I believe you're using the image_cropper library (https://pub.dev/packages/image_cropper), which is under the BSD License - this requires that you include the License in your app somehow, but I don't know whether this is relevant for the contest. Just make sure to include it if you decide to publish your app.
2. The app asks for external storage permissions when importing from the gallery, which is suboptimal, because the app shouldn't need access to the entire storage. Instead, it could for example make use of an intent, which would grant the app permission to read the URI of the image selected by the user.

Maybe I'm missing something, but it seems like you can only add one emoji to each sticker instead of multiple ones.

I can only add one emoji to each sticker. :(

Also the application is slow when ever my data is on
