# Runtime Considerations for Flows That Include Aura Components

Depending on where you run your flow, Aura components may look or behave differently than expected. The flow runtime app that's used for some distribution methods doesn't include all the necessary resources from the Lightning Component framework. When a flow is run from Flow Builder or a direct flow URL (<https://yourDomain.my.salesforce.com/flow/MyFlowName>), `force` and `lightning` events aren’t handled.

To verify the behavior of your Aura components, test your flow in a way that handles `force` and `lightning` events, such as `force:showToast`. You can also add the appropriate event handlers directly to your component.
