This folder contains all ui components that are necessary to display the keyboard accessory bar and the accessory bottom sheet. They are mainly used for autofill- and password-related tasks.
The ManualFillingCoordinator in this package uses the bar_component.* to display a bar above an open keyboard. This bar shows suggestions and holds a number of tabs in a tab_layout_component.* which allows to open an accessory sheet with fallback data and options. The sheet is located in the sheet_component.* and shows one of the tabs as defined in sheet_tabs.*. The responsibility of the ManualFillingCoordinator is to integrate the active sub components with the rest of chromium (e.g. Infobars, popups, etc.) and ensure that they are perceived as extension or replacement of the keyboard.
The data.* package provides helper classes that define the data format used by all components. They support data exchange by providing generic Providers and simple implementations thereof.
Ideally, components only communicate by interacting with the coordinator of one another. Their inner structure (model, view, view binder and properties) should remain package-private. For some classes, this is still an ongoing rework.
There are two versions of the accessory that share a most components.
Version V1 of the manual filling component supports only filling password fields and introduces password generation. Enable it with these flags:
Version V2 of the manual filling component supports filling every form field where autofill is available with autofill suggestions or fallback data. It applies Chrome's modern design. To enable it, set these flags:
