Implementation

@override
Widget build(BuildContext context) {
  return LayoutBuilder(
    builder: (context, constraints) {
      // Calculate the visible text scale factor.

      final nr = (constraints.maxWidth * constraints.maxHeight);
      const dr =
          kTextScaleFactorReferenceWidth * kTextScaleFactorReferenceHeight;
      final textScaleFactor = sqrt((nr / dr).clamp(0.0, 1.0));

      final textScaler = widget.configuration.textScaler ??
          TextScaler.linear(textScaleFactor);
      return Material(
        color: Colors.transparent,
        child: AnimatedContainer(
          padding: padding,
          duration: duration,
          alignment: Alignment.bottomCenter,
          child: Text(
            [
              for (final line in subtitle)
                if (line.trim().isNotEmpty) line.trim(),
            ].join('\n'),
            style: widget.configuration.style,
            textAlign: widget.configuration.textAlign,
            textScaler: textScaler,
          ),
        ),
      );
    },
  );
