UltravioletTuiRenderer class

Ultraviolet-inspired renderer backed by a cell buffer + diffing updates.

This renderer keeps Model.view(): String as the public API, but internally parses ANSI-styled strings into a cell buffer and diffs frames to emit minimal terminal updates.

In full-screen mode this writes UV output directly to the terminal. In inline mode it captures UV output first, rewrites absolute row-addressing escape sequences into the configured inline region, and then restores the surrounding CLI cursor position.

UltravioletTuiRenderer({required TuiTerminal terminal, TuiRendererOptions options = const TuiRendererOptions(), ({bool useBackspace, bool useTabs})? movementCapsOverride})

Creates a UV renderer targeting the given terminal.

Properties

hashCode → int

The hash code for this object.

no setter, inherited

metrics → RenderMetrics?

Returns the render metrics from the underlying UV renderer.

no setter, override

movementCapsOverride → ({bool useBackspace, bool useTabs})?

Optional override for terminal movement capabilities.

final

runtimeType → Type

A representation of the runtime type of the object.

no setter, inherited

screenBuffer → ScreenBuffer?

The current screen buffer, populated after each render/flush cycle.

no setter

terminal → TuiTerminal

The terminal to render to.

final

Methods

captureNativeCellDelta() → TerminalNativeCellDeltaFrame?

Captures the renderer's most recent changed-cell delta, if available.

captureNativeDelta() → TerminalNativeDeltaFrame?

Captures the renderer's most recent dirty-line delta, if available.

captureNativeFrame() → TerminalNativeFrame?

Captures the renderer's current native frame, if available.

clear() → void

Clears the rendered content.

override

dispose() → void

Disposes of renderer resources.

override

flush() → Future<void>

Flushes any buffered output.

override

initialize() → void

Initializes terminal state needed before the first render.

override

invalidate() → void

Resets internal diff / cache state so the next render call produces a full redraw, without performing any terminal I/O.

override

noSuchMethod(Invocation invocation) → dynamic

Invoked when a nonexistent method or property is accessed.

inherited

printLine(String text) → void

Appends text as persistent log line(s) above the rendered view.

render(Object view) → void

Renders the view to the terminal.

override

renderImmediate(String view) → void

Renders view immediately, bypassing frame-rate limiting.

setNativeFrameCaptureEnabled(bool enabled) → void

Enables native frame capture during subsequent render flushes.

toString() → String

A string representation of this object.

Operators

operator ==(Object other) → bool

The equality operator.
