buildControls method

List<Widget> buildControls(BuildContext context)

Builds the list of control widgets.

Returns a retry button when showRetry is true, or the standard refresh + primary-action Row when showControls is true. Returns an empty list when neither flag is set.

Implementation

List<Widget> buildControls(BuildContext context) {
  final controls = <Widget>[];

  if (showRetry) {
    controls.add(
      _wrapSemantics(
        identifier: retrySemanticsIdentifier,
        label: retrySemanticsLabel ?? retryText,
        child: ButtonPrimary(
          text: retryText,
          onTap: onRetry,
        ),
      ),
    );
  } else if (showControls) {
    final int secondaryFlex =
        formFactor == CloudPosDisplaySize.xSmall ? 2 : 1;
    final int primaryFlex =
        formFactor == CloudPosDisplaySize.xSmall ? 3 : 6;
    controls.add(
      Row(
        children: [
          Expanded(
            flex: secondaryFlex,
            child: _wrapSemantics(
              identifier: refreshSemanticsIdentifier,
              label: refreshSemanticsLabel ?? 'Refresh',
              child: ButtonSecondary(
                text: '',
                icon: refreshIcon,
                onTap: onRefresh,
              ),
            ),
          ),
          const SizedBox(width: 8),
          Expanded(
            flex: primaryFlex,
            child: _wrapSemantics(
              identifier: primaryActionSemanticsIdentifier,
              label: primaryActionSemanticsLabel ?? primaryActionText,
              child: ButtonPrimary(
                text: primaryActionText,
                disabled: primaryActionDisabled,
                onTap: onPrimaryAction,
              ),
            ),
          ),
        ],
