flavor 1.0.0

An easy way to configure flavor settings and displaying flavor banner.

flavor

A Flutter plugin for configuring flavor settings and optionally display a flavor banner on the app.

Flavors

Each app needs some kind of flavor during its development lifecycle. You often have an api you use that is different during dev, beta, production, or log settings for example. That's when flavors come in.

Setup flavors

You can define different start main methods, each can be configured with a flavor.

So for example, you can create a main_dev.dart file for your development environment:

void main() {
  Flavor.create(
    Environment.dev,
    color: Colors.green,
    name: 'PREVIEW',
    properties: {
      Keys.apiUrl: 'https://api.dev.company.com',
      Keys.apiKey: 'jksdhfkjhs83rjkh324kj23h4',
      logLevelKey: 100,
    },
  );
  setupApp();
}

And a main_prod.dart file for your production environment:

void main() {
  Flavor.create(
    Environment.production,
    properties: {
      Keys.apiUrl: 'https://api.company.com',
      Keys.apiKey: 'lksdhjfkjhdsf8sdfjkhsdf896',
      logLevelKey: 5,
    },
  );
  setupApp();
}

Each of these files will point to another main.dart file:

void setupApp() {
  final logLevel = Flavor.I.getInt(logLevelKey);
  print('LogLevel set for this flavor: $logLevel');
  runApp(FlavorApp());
}

You can also define additional properties for each flavor/configuration. This is handy to store url's, api keys, etc. Further in your app you can access these values.

Flavor.I.getString(Keys.apiUrl)

Or you can check what flavor is currently running:

if (Flavor.I.isDevelopment) {
// do something nice in development
}

Checkout the examples folder for a complete setup.

Note: If you want to change bundle ids, or even assets (icon, splash screen) check out flutter_flavorizr. This nice tool will help you create flavors in Android and iOS.
