Flutter： Unsupported value: false/true

Posted 2022-06-24 一叶飘舟

在使用FlutterBoost传参时，直接传递bool值时出现崩溃。

FlutterBoost.singleton.open(
            'flutter://personnel_page',
            urlParams: <String, dynamic>
              'isBd': i%2==0 ? true : false,
  
            ,
          ),

崩溃日志如下：

原以为是FlutterBoost框架的bug，百度了一番，原来是低版本flutter的bug。

这个是因为StandardMessageCodec的boolean检查有问题导致Native像Flutter传参map里value有boolean的时候崩溃，commit已经merge到master了

高版本还没有验证...
