AnsiTerminalDriver class abstract
A TerminalDriver base that turns ScreenBuffer frames into ANSI byte output, leaving the byte sink, size, and input/resize streams to subclasses.
The alternate-screen / SGR / cursor sequences and the frame diffing are
identical for every terminal, so they live here once and are shared by the
native TTY driver (Terminal, which writes to stdout and manages raw mode)
and browser drivers (which write to a terminal widget). Subclasses implement
writeAnsi (the sink) plus size/input/resizeEvents (from
TerminalDriver), and may override onEnter/onLeave for sink-specific
setup such as raw mode or flow control.

Methods
-
enter(
) → void -
Enters full-screen mode (alternate screen + raw input).
override
-
invalidate(
) → void -
Forces the next present to repaint in full.
override
-
leave(
) → void -
Leaves full-screen mode, restoring the prior screen and input mode.
override
-
noSuchMethod(
Invocation invocation) → dynamic -
Invoked when a nonexistent method or property is accessed.
inherited
-
onEnter(
) → void - Hook run during enter, before the alternate-screen sequence is written (e.g. enable raw mode / disable flow control). Default: no-op.
-
onLeave(
) → void - Hook run during leave, after the screen-restore sequence is written (e.g. restore the previous input mode). Default: no-op.
-
present(
ScreenBuffer frame, {int? cursorX, int? cursorY}) → void -
Renders
frame, diffed against the previous one, optionally placing the hardware cursor.override -
toString(
) → String -
A string representation of this object.
inherited
-
writeAnsi(
String ansi) → void -
Writes
ansi(already-encoded escape/text) to the underlying terminal.
Operators
-
operator ==(
Object other) → bool -
The equality operator.
