Flutter domain manager

Easily add subdomain specific logic in your Flutter web app

Setup

Add to pubspec.yaml

flutter_domain_manager: ^0.0.3

Using

Call this somewhere in the beginning of your code, in the example it is called in main.dart inside main() before runApp(). It could be placed somewhere else.

DomainManager.register(
  config: DomainManagerConfig(
    domain: "https://app.iconica.nl/",
    allowedCompanies: ["iconica"],
    debugCompany: "iconica",
  ),
);

domain: Root domain where the base app is hosted, used for validation and redirection

allowedCompanies: List of allowedCompanies, if empty anything is allowed.

debugCompany: Used for development, since the Flutter debugger doesn't act great when adding a subdomain to localhost

Attention

To use this in production more setup is required, look at app_server for more information

Motivation

The motivation behind this package in one sentence is:

Easily support multi tenancy in your Flutter web app with minimal deployments and DNS changes

For our application we want to offer multi-tenancy as a feature, this should be achieved in the easiest way possible. We DON'T want to have to do the following:

• Set up N amount of clients
• Add lots of DNS records
• Manage lots of subdomains

This package in combination with this Allows you to have multi-tenant support whilst only having to add 2 DNS records.

The primary use case for this will be with Firebase APP hosting, since this allow wildcard subdomains (Firebase hosting does not allow this).

Setup

• Create a Flutter site
• Use flutter_domain_manager for retrieving the proper tenant and configuring it
• Setup app server inside the project
• Initialize and create the app hosting backend with the command under Deploying
• Add the following custom domains to your backend service:
  • *.iconica.nl
  • iconica.nl

This last step can be personalized, so an already defined subdomain can be setup:

• *.app.iconica.nl
• app.iconica.nl

Also environments could be added in this way:

• *.app.staging.iconica.nl
• app.staging.iconica.nl

So, lots of possibilities!
