But in my android folder shows unused dependencies . Anyone can explain this and how to remove this from project ? Ex:package_info_plus
...ANSWER
Answered 2022-Mar-29 at 06:43I am not sure if I am giving the correct answer but, this may be because each flutter package/plugin may depend on others. If you see the device_info_plus on pub.dev you will see its dependencies. See the below image.
QUESTION
Because every version of anyline depends on permission_handler ^5.0.1+1 and motorgate depends on permission_handler ^8.3.0, anyline is forbidden. So, because motorgate depends on anyline ^24.0.0-dev.1, version solving failed. pub get failed (1; So, because motorgate depends on anyline ^24.0.0-dev.1, version solving failed.)
...ANSWER
Answered 2021-Dec-06 at 14:12anyline is outdated and not compatible with your other packages. You would have to downgrade permission_handler to version ^5.0.1+1 to be compatible, but this could cause other problems.

My application is to search through the list of books. Two different variables (book name or barcode) can be used while searching. There is no problem when searching by name. but when searching with barcode scanning, no results are listed. When I type the barcode manually, the application still works without any problems.
Can u help me?

Answered 2021-Nov-04 at 19:04I think you only need a listener for your TextEditingController. And you should write your onChanged method inside that listener.

QUESTION
I'm building a 2FA application, which scans a QR code. Then it parses the uri inside QR code and returns a totp code. However, I have a problem closing the CupertinoActionSheet using Navigator.of(context).pop().
I want it to work like that:
- When a user taps on "add" button, the Action Sheet shows up.
- When user clicks on "Scan QR code", the Action Sheet must close and then proceed with scanning.
Here's the error that shows ups when I have the code below: "Looking up a deactivated widget's ancestor is unsafe. At this point the state of the widget's element tree is no longer stable. To safely refer to a widget's ancestor in its dispose() method, save a reference to the ancestor by calling dependOnInheritedWidgetOfExactType() in the widget's didChangeDependencies() method."

Answered 2021-Mar-08 at 19:23I believe that the problem lies within this code fragment:
QUESTION
I'm using stripe payment gateway in my app everything works fine when i enter card details after that it redirect to the OTP page after enter otp and submit it throws this error
This problem occurs only in live mode, in test mode debit card won't ask for OTP
...ANSWER
Answered 2020-Oct-07 at 16:20Assuming that "OTP" is a "one time password" as part of a 3D Secure flow, then you can trigger this in test mode by using the SCA regulatory test cards such as the 3155 or 3184 card.
It's not clear where your error is coming from, but if you can share more detail with reproduction in test mode then someone may be able to offer more suggestions.
