render method

@override void render(Object view)

Renders the view to the terminal.

view is the string representation of the current UI state, or a View object containing metadata.

Implementation

@override
void render(Object view) {
  _metrics.beginFrame();

  if (!_initialized) {
    initialize();
  }

  final String content = switch (view) {
    String s => s,
    View v => v.content,
    _ => view.toString(),
  };

  // Frame rate limiting
  if (_lastRenderTime != null) {
    final elapsed = DateTime.now().difference(_lastRenderTime!);
    if (elapsed < _options.frameTime) {
      // Skip this frame
      _metrics.endFrame(skipped: true);
      return;
    }
  }

  // Skip if view hasn't changed
  if (content == _lastView) {
    _metrics.endFrame(skipped: true);
    return;
  }

  // Full redraw (future: diff with _lastView and update only changed lines)
  terminal.cursorHome();
  final output = _options.ansiCompress ? compressAnsi(content) : content;
  terminal.write(output);

  // Clear any remaining content from previous render
  _clearToEndOfScreen(content);

  _lastView = content;
  _lastRenderTime = DateTime.now();
  _metrics.endFrame();
}
