ProgressRing

A circular progress indicator. Leave value unset for an indeterminate spinner, or set it (0.0–1.0) for determinate progress. Use progress_bar for a linear bar.

Example

# indeterminate spinner
progress_ring()

# determinate (60%)
progress_ring(value: 0.6, stroke_width: 4)

Common properties

• value — nil (spinner) or 0.0–1.0
• color
• bgcolor
• stroke_width
• stroke_cap
• stroke_align
• semantics_label

Usage

Show a spinner while loading, then swap in content:

body = column(children: [progress_ring()])
page.add(body)

records = load_records          # slow work
page.update(body, children: records.map { |r| text(r.name) })

For a horizontal bar, progress_bar(value: 0.6).
