feature_flags #

This package simply allows you to activate dynamically functionnalities of your app.

Usage #

Setup #

Wrap your app's widget in a Features widget.

Features(
    child: MaterialApp(
        /// ...
    ),
);

Testing if a feature is enabled #

To test is a feature is currently enabled, use the Features.isFeatureEnabled function with a unique functionnality identifier.

if (Features.isFeatureEnabled(context, 'DECREMENT')) {
    /// The 'DECREMENT' feature is enabled
}

Enable or disable a feature #

From the Features widget #

By updating the flags from the Features widget.

Features(
    flags: [ 'DECREMENT' ],
    child: MaterialApp(
        /// ...
    ),
);

Enabling it locally from code #

You can activate a feature by calling the Features.setFeature function. The feature flag is saved into shared preferences and is persisted between sessions.

Features.setFeature(
    context,
    'DECREMENT',
    true,
);

Using the debug view #

The debug view allow your users to activate or deactivate any dynamic feature.

This may be useful during developpment, but it should be used carefuly.

DebugFeatures.show(
    context,
    availableFeatures: [
        Feature('DECREMENT', name: 'Decrement'),
        Feature('RESET', name: 'Reset'),
    ],
);
