TerminalPainter class

Paints the terminal grid (backgrounds + glyphs + decorations) — everything except the cursor, which lives on its own CursorPainter layer so the blink timer doesn't repaint the whole grid. Repaints only on grid mutation.

Inheritance

Constructors

TerminalPainter({required MirrorGrid grid, required GlyphCache glyphs, required double cellWidth, required double cellHeight, required int selectionColor, required SearchColors searchColors, required HintColors hintColors, LinkOverlay linkOverlay = LinkOverlay.empty, GlyphAtlas? atlas, double backgroundOpacity = 1.0})

Properties

atlas → GlyphAtlas?
When non-null, glyphs are batched through this atlas with a single drawRawAtlas per frame instead of one drawParagraph per cell. Glyphs not yet in the atlas fall back to glyphs/drawParagraph for one frame while the atlas grows.
final
backgroundOpacity → double
Opacity 0,1 of the terminal's default background. 1.0 (default) makes the grid layer fully opaque, so the widget is self-contained — it does NOT rely on a host-provided background behind it. < 1.0 lets whatever is behind the widget show through the default-bg regions (a translucent terminal).

Methods

addListener(VoidCallback listener) → void
Register a closure to be notified when it is time to repaint.
inherited
hitTest(Offset position) → bool?
Called whenever a hit test is being performed on an object that is using this custom paint delegate.
inherited
noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
inherited
paint(Canvas canvas, Size size) → void
Called whenever the object needs to paint. The given Canvas has its coordinate space configured such that the origin is at the top left of the box. The area of the box is the size of the size argument.
override
removeListener(VoidCallback listener) → void
Remove a previously registered closure from the list of closures that the object notifies when it is time to repaint.
inherited
shouldRebuildSemantics(covariant CustomPainter oldDelegate) → bool
Called whenever a new instance of the custom painter delegate class is provided to the RenderCustomPaint object, or any time that a new CustomPaint object is created with a new instance of the custom painter delegate class (which amounts to the same thing, because the latter is implemented in terms of the former).
inherited
shouldRepaint(covariant TerminalPainter old) → bool
Called whenever a new instance of the custom painter delegate class is provided to the RenderCustomPaint object, or any time that a new CustomPaint object is created with a new instance of the custom painter delegate class (which amounts to the same thing, because the latter is implemented in terms of the former).
override
toString() → String
A string representation of this object.

Operators

operator ==(Object other) → bool
The equality operator.
