Here is an example to remove "bla_" form the following files:

bla_1.txt
bla_2.txt

FWIW: I'm not the author of the content presented here (which is an outline from Edmond Lau's book). I've just copy-pasted it from somewhere over the Internet, but I cannot remember what exactly the original source is. I was also not able to find the author's name, so I cannot give him/her the proper credits.

Note that local_auth plugin requires the use of a FragmentActivity as opposed to Activity. This can be easily done by switching to use FlutterFragmentActivity as opposed to FlutterActivity in your manifest (or your own Activity class if you are extending the base class).

1. Open android>app>src>main>AndroidManifest.xml

Add USE_FINGERPRINT permission.

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
          package="com.[your.package]">
  <uses-permission android:name="android.permission.USE_BIOMETRIC"/>

This is the runnable sample code from the blog post [Patterns for security with Firebase Authentication: offload work to Cloud Functions][1]. It discusses offloading work from a client app to Cloud Functions using an authentication trigger.

1. Create a new Firebase project
2. Enable email/password authentication
3. Provision Cloud Firestore and apply the rules given in this gist
4. Use the Firebase CLI to create a workspace for Functions using TypeScript
5. Deploy the given HTML and JavaScript to Firebase Hosting (the CLI emulator will also work).
6. Deploy the function code to Cloud Functions using the Firebase CLI
