  bool shouldLog(LogEvent event) {
    return true;
  }
}

  @override
  void log(LogEvent event) {
    println(event.message);
  }
}

Examples

CustomRadio<String, double>(
  value: 'First',
  groupValue: widget.radioValue,
  duration: Duration(milliseconds: 500),
  animsBuilder: (AnimationController controller) => [
    CurvedAnimation(
      parent: controller,
      curve: Curves.easeInOut
    )
  ],
  builder: (BuildContext context, List<double> animValues, Function updateState, String value) {
    final alpha = (animValues[0] * 255).toInt();
    return GestureDetector(
      onTap: () {
        setState(() {
          widget.radioValue = value;
        });
      },
      child: Container(
        padding: EdgeInsets.all(32.0),
        margin: EdgeInsets.all(12.0),
        alignment: Alignment.center,
        decoration: BoxDecoration(
          shape: BoxShape.circle,
          color: Theme.of(context).primaryColor.withAlpha(alpha),
          border: Border.all(
            color: Theme.of(context).primaryColor.withAlpha(255 - alpha),
            width: 4.0,
          )
        ),
        child: Text(
          value,
          style: Theme.of(context).textTheme.body1.copyWith(fontSize: 24.0),
        )
      )
    );
  }
)

But any combination of animation types are supported.
CustomRadio<String, dynamic>(
  value: 'First',
  groupValue: widget.radioValue,
  animsBuilder: (AnimationController controller) => [
    CurvedAnimation(
      parent: controller,
      curve: Curves.easeInOut
    ),
    ColorTween(
      begin: Colors.white,
      end: Colors.deepPurple
    ).animate(controller),
    ColorTween(
      begin: Colors.deepPurple,
      end: Colors.white
    ).animate(controller),
  ],
  builder: (BuildContext context, List<dynamic> animValues, Function updateState, String value) {
    return GestureDetector(
      onTap: () {
        setState(() {
          widget.radioValue = value;
        });
      },
      child: Container(
        alignment: Alignment.center,
        margin: EdgeInsets.all(18.0),
        padding: EdgeInsets.all(32.0 + animValues[0] * 12.0),
        decoration: BoxDecoration(
          shape: BoxShape.circle,
          color: animValues[1],
          border: Border.all(
            color: animValues[2],
            width: 2.0
          )
        ),
        child: Text(
          value,
          style: Theme.of(context).textTheme.body1.copyWith(
            fontSize: 20.0,
            color: animValues[2]
          ),
        )
      )
    );
  },
