Hi Everyone ,
I tried of downloading 123RFID sdk which is in Java but i am supposed to implement it in Flutter .
The package Zebra_rfid for flutter in Pub.dev has a repo of github and the sample code to establish the connection with RFID device but it has an error

Hi,
What device are you running on? Looks like the RFID service isn't present on the device.
Using the device TC26
The TC26 doesn't have RFID support - you'll either need to use something like an RFD40 / RFD2000 to enable RFID.
Sorry , I am Using
RFD4030 - G00B700-IN
Looks like the flutter wrapper is using V2.0.1.29 of the RFID3 SDK. RFD40 support was added in V2.0.1.44 - please use at least this version, or ideally the latest version, available here: https://www.zebra.com/us/en/support-downloads/software/developer-tools/…
Thank you but they are all for the sdk of Android in Java , I want a solution for Flutter in dart.
We don't officially support Flutter for our SDKs. You would need to modify the wrapper you're using from pub.dev to use the latest version of the SDK. It should be as straight forward as just replacing the .aar file in the wrapper with the latest versions - there shouldn't be any code changes required as the APIs are backwards compatible.
Okay,
Can you assist me how can we change the wrapper ?
That would be helpful for us and our team .
Replace the .aar file in this directory with the latest version then recompile the library
I replaced the latest .aar file (API3_LIB-release-2.0.2.94)
but still got same issue .

Can you please try running the native sample & see if you get the same error?
Could you try adding the below to your manifest to see if that works?
