A widget that will display a pop-up for an individual feature. This includes showing the feature's title, attributes, custom description, media, and attachments.

The new online Map Viewer allows users to create a pop-up definition by assembling a list of pop-up elements. PopupView will support the display of pop-up elements created by the Map Viewer, including: Text, Fields, Attachments, and Media (Images and Charts).

Overview

Thanks to the backwards compatibility support in the API, it will also work with the legacy pop-up definitions created by the classic Map Viewer. It does not support editing.

Features

• Display a pop-up for a feature based on the pop-up definition defined in a web map.
• Supports image refresh intervals on image pop-up media, refreshing the image at a given interval defined in the pop-up element.
• Supports elements containing Arcade expression and automatically evaluates expressions.
• Displays media (images and charts) full-screen.
• Supports hyperlinks in text, media, and fields elements.

Usage

The PopupView contains:

• A header section with title defined in the Popup.
• A body, built using a Column and combination of Card and ExpansionTile widgets, consisting of different types of pop-up elements, including text (HTML), fields, media, and attachments.

A pop-up is usually obtained from an identify result and then a PopupView can be created to wrap the pop-up and display its contents in a sized widget, such as a Dialog or a Container:

PopupView(
  popup: popup,
  onClose: () {
    // Optional: handle close action
  },
)
