Screen flow input, navigation, and Lightning page placement
Key Takeaway
On a Record page, the Flow component can pass the current record into a flow variable named recordId that is available for input. A Text variable receives the record ID, and a record variable receives all field values.
A screen flow is a flow that shows users pages, called screens, where they read information or enter answers. The flow then uses those answers to update data, send communications, or show more questions. As the admin, you decide what each screen collects and which navigation buttons appear. You also decide where the flow appears, such as embedded on a Lightning page.
How screens work
The Screen element is the only flow element users see when the flow runs. Each screen is one page the user sees, and each one comes from a single Screen element. So a flow with several pages needs several Screen elements. A screen is still called a screen even when the flow fills only a small part of the Salesforce window.
When a flow reaches a Screen element, the flow stops and waits for the user. After the user clicks "Next", the flow continues down its path.
