How to add fingerprint scanner in flutter app - flutter

I am trying to add fingerprint authentication in my screen app by using local_auth package in flutter.. but my device doesn't support fingerprint... my android version is 7.1.1 ... is there a way to add authentication using fingerprint when device doesn't support?.. or is there a package in flutter to add fingerprint scanner

No, because your device will not be able to read your biometrics. No lib can help you with that.

Implementing google login flutter gives 12500 error

I implemented google login in flutter without using firebase in flutter (google cloud console). It was working in apk then later I needed push notification service for which I used firebase (fcm token and all) then I released the app to playstore but google login does not work. I keep getting apiexception error. Has anybody faced this issue? if yes any help would be highly appreciated.
I do not have a specific answer to your problem but I have also faced this problem once, I accidentally resolved it though.
But Error 12500 is a general error code that may occur when attempting to use the Google Sign-In feature and is caused by a few potensial issues:
An issue with the SHA-1 fingerprint of your app's signing
certificate: To use Google Sign-In, you need to configure your app's
SHA-1 fingerprint and package name in the Firebase console. Make
sure that the fingerprint and package name you have configured in
the Firebase console match the ones you are using to sign your app.
An issue with the Google Services configuration file: Make sure you
have properly added the Google Services configuration file to your
app.
An issue with the Google Play Services library: Make sure you have
the latest version of the Google Play Services library installed in
your app.
An issue with the device or emulator you are using: Make sure you
are testing on a device or emulator that has Google Play Services
installed and is up to date.
Possible fixes to try/check:
Double-check the SHA-1 fingerprint and package name: Make sure that
the SHA-1 fingerprint and package name you have configured in the
Firebase console match the ones you are using to sign your app.
Make sure you have added the Google Services configuration file: The
Google Services configuration file is required for your app to
communicate with Google services, including Google Sign-In. Make
sure you have properly added this file to your app.
Update the Google Play Services library: Make sure you have the
latest version of the Google Play Services library installed in your
app. You can check for updates by going to the "SDK Manager" in
Android Studio.
Test on a device or emulator with Google Play Services installed:
Make sure you are testing on a device or emulator that has Google
Play Services installed and is up to date.
I hope this helps! I will quickly search if I can find any other solution.

Flutter - Can't install apk on android

I'm new to flutter and on a phone I have it works and the app runs fine, but I sent the apk to another device and it couldn't be installed, I don't know if it's because of a plugin I'm using that is "speech to speech", since in that plugin I changed the version of min sdk to 21 but the android that I try to install has an android version of 10 that is higher, it seems to me, what would be the cause?
Remember Android no longer accept the app which has not been signed as release,. make sure you are making you are signing the app correctly, Android studio will help you.
The build flavor should be release, and the signature must be created before. But the easiest way is to run the app in profile mode,
flutter run --profile
Profile mode run as release mode but doesn't require to be manually signed.
There could be other reasons but do you know that the Flutter app cannot be installed on x86 Android
Flutter does not currently support building for x86 Android

How to sign and align an android application generated by Intel XDK?

I want to use my custom keystore in this project because I intend to host the application in PlayStore and keep it updated. Without the keystore will be tricky.
Details: In the settings cordova, I not marked the "Signed" box and I exported the app and tried signing it using javasign. At the command prompt went well but the app does not install on any of the devices I tested.
The APK created by the Intel XDK is created using standard Cordova CLI. So the techniques you would use to sign that APK are no different than what you would use with any other Cordova (or PhoneGap) app or an APK built using Eclipse or any other tools.
