I have tried with these blocks and works fine…
1. Blocks section
2. App Response as per the above blocks
(i painted on personal informations, sorry for that)
Here i have used three labels
In label1 - Name of the image
In Label 2 - Saved image path url
In label 3 - If error occur with crop view
( for cross check i used, while compiling i will remove all the label and you do too)
3. Image stored in phone memory
Here you can use tinyDB to give number. If not cropped image will overwrite in the existing image
4. Image details
Please try like this, and still error persist please ask here. IF it solves, please dont forget to hit solution icon.
