Image upload feature using bloc library.
This project demonstrate how to use bloc to implement image uploading features. It has 3 Event which is GalleryImagePicked , CameraImagePicked, and ImageDeleted which occurs when you pressed each one of it corresponding button (add image from gallery, add image from camera, and delete image).
The ImagePickerBloc then will handle the event and doing the image uploading process, yield ImagePickerSuccess state or deleting it and yield ImagePickerEmpty state.
The UI will show the uploaded image and delete button when the state is ImagePickerSuccess and showing no picture when the state is ImagePickerEmpty.
