allowBackup is not working for IOS

[sudeekshachip1003]

I tried to add allowBackup optional parameter for isAvailable, but isAvailable is not accepting any param. Anything else to be done to enable backup option(passcode) for IOS?

cordova-plugin-fingerprint-aio : 4.0.2
@ionic-native/fingerprint-aio : 5.33.0

That's rather a problem in Ionic wrapper than in the plugin - types in it are outdated and don't match the latest plugin version. In order to specify allowBackup, you can use plugin directly, e.g.:

(window as any).Fingerprint.isAvailable((result: string) => {
  resolve(result);
}, (errorObject: {code: string, message: string}) => {
  reject(new Error(errorObject.message));
}, {
  allowBackup: true
});
