Constructors

MirrorGrid({int defaultFg = 0xD8D8D8, int defaultBg = 0x181818})

defaultFg/defaultBg fill empty/newly-grown cells. They must match the engine's blank-cell colors (the configured default fg/bg) so untouched rows — which the engine never sends partial damage for — render in the right color from the first frame instead of a stale hardcoded default.

Properties

columns → int

no setter, override

cursorBlinking → bool

no setter, override

cursorCol → int

no setter, override

cursorColor → int

Program-set cursor color (OSC 12), or 0xFF000000 (kCursorColorUnset) when unset — in which case painters keep their inverse-video cursor.

no setter, override

cursorRow → int

no setter, override

cursorShape → int

no setter, override

cursorVisible → bool

no setter, override

displayOffset → int

no setter, override

generation → int

Bumps on every apply / initializeEmpty; used by TerminalPainter.shouldRepaint.

no setter, override

hashCode → int

The hash code for this object.

no setter, inherited

hasListeners → bool

Whether any listeners are currently registered.

no setter, inherited

modeFlags → int

no setter, override

rows → int

no setter, override

runtimeType → Type

A representation of the runtime type of the object.

no setter, inherited

scrollFraction → double

Sub-cell scroll offset in [0.0, 1.0): how far the viewport is scrolled up past a line boundary, in fractions of a cell height. The painter shifts content down by scrollFraction * cellHeight and fills the revealed top sliver with the overscan row (cell row == -1). 0.0 on a line boundary.

no setter, override

Methods

addListener(VoidCallback listener) → void

Register a closure to be called when the object changes.

inherited

apply(GridUpdate u) → void

bgAt(int row, int col) → int

override

codepointAt(int row, int col) → int

Cell accessors. row in 0..rows-1 reads the viewport; row == -1 reads the overscan line (the row just above the viewport top) used to paint the scrollFraction sliver. Other negative rows are not valid.

override

dispose() → void

Discards any resources used by the object.

inherited

fgAt(int row, int col) → int

override

flagsAt(int row, int col) → int

override

hyperlinkIdAt(int row, int col) → int

override

initializeEmpty(int rows, int columns) → void

Empty viewport for startup — avoids a sync full_snapshot FFI round-trip.

noSuchMethod(Invocation invocation) → dynamic

Invoked when a nonexistent method or property is accessed.

inherited

notifyListeners() → void

Call all the registered listeners.

inherited

removeListener(VoidCallback listener) → void

Remove a previously registered closure from the list of closures that are notified when the object changes.

inherited

toString() → String

A string representation of this object.

Operators

operator ==(Object other) → bool

The equality operator.
