Create Android App in Firebase Project

After creating a firebase project, in this project we can create several apps with different configuration, here we will create Hallo Doctor Client Android App.

Create Hallo Doctor Client Android App

• Click android icon

• After that we are required to fill in three information about our app, Package Name, App Name, and SH1 Key

  

• first we need the package name of our app, to get the package name of our app

Get Package name

• in your Project Flutter Hello Doctor Client, which was already open using visual studio code, or Android Studio

info

make sure you've downloaded all the dependencies in this project, by running flutter pub get command

• we will change the default package name of this app to your package name, this will be very easy and fast because this project already uses change_app_package_name flutter package https://pub.dev/packages/change_app_package_name

• run the command below, but first change com.mycompany.myappname, to your package name

flutter pub run change_app_package_name:main com.mycompany.myappname

• if successful it will look like this

• so after that, the package name in your Hello Doctor Client app has all changed, and you can copy the package name to firebase
• and add your App nickname

• for debug signing, we can fill it later, just click register app

• after that you have to download the google-service.json file

• and copy the file into your app project in the directory android/app/

info

if in that folder there is already a google-service.json file change it to your file which you just downloaded, and make sure there is no typo in the filename google-service.json

• after that click next in firebase,

• and click Continue to console

• congratulation your app is now registered
• but we need to enable some Firebase features for our app, like authentication, so we can login, continue to the next section
