ProgramRenderCapture class final
Bundles deterministic snapshot recording with aggregate render monitoring.
This is useful for tests and tooling that want both frame-by-frame evidence and a compact summary without wiring two interceptors manually.

Methods
-
clear(
) → void - Removes all recorded snapshots and resets aggregated monitor state.
-
lastSnapshotSummary(
{int maxFrameLines = 3}) → ProgramRenderSnapshotSummary? - Compact summary of the last captured snapshot, if any.
-
noSuchMethod(
Invocation invocation) → dynamic -
Invoked when a nonexistent method or property is accessed.
inherited
-
onProcessed(
Msg msg, Duration elapsed) → void -
Called after a message has been processed.
inherited
-
onRendered(
{required int renderGeneration, required Object view, required DegradationLevel degradationLevel, required Duration renderDuration, int? width, int? height, TerminalNativeFrame? nativeFrame, TerminalNativeDeltaFrame? nativeDelta, TerminalNativeCellDeltaFrame? nativeCellDelta, List< TerminalNativeSpanDelta> ? nativeSpanDelta}) → void -
Called after a render has completed.
override
-
onSend(
Msg msg) → Msg? -
Called for each message before it is queued.
inherited
-
onStart(
void send(Msg msg)) → void -
Called once after program initialization.
inherited
-
onStop(
) → void -
Called during program cleanup.
inherited
-
payload(
{String prefix = 'Render', int maxFrameLines = 3}) → ProgramRenderCapturePayload - Builds a serialization-friendly payload for the whole capture state.
-
report(
{String prefix = 'Render', int maxFrameLines = 3}) → ProgramRenderCaptureReport - Builds a structured summary of the latest capture state.
-
snapshotsSince(
int generation) → List< ProgramRenderSnapshot> -
Returns snapshots whose render generation is greater than
generation. -
toJson(
{String prefix = 'Render', int maxFrameLines = 3}) → Map< String, Object?> - Builds a serialization-friendly payload for the whole capture state.
-
toMetricEntries(
{String prefix = 'Render'}) → Map< String, String> - Formats aggregate render metrics for diagnostics or overlays.
-
toReportLines(
{String prefix = 'Render', int maxFrameLines = 3}) → List< String> - Builds a compact text report combining snapshot and aggregate state.
-
toString(
) → String -
A string representation of this object.

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