flutter填坑——解决ListView添加在Scaffold上默认的的top-padding

解决方法

把ListView用MediaQuery.removePadding组件包裹，并设置removeTop为true

    child: new MediaQuery.removePadding(
              removeTop: true,
              context: context,
              child: ListView.builder(
                itemCount: _dataSource.length,
                itemBuilder: (BuildContext context, int index){
                  return Material(
                    color: Colors.green,
                    child: ListTile(
                      title: Text(_dataSource[index]),
                    ),
                  );
                },
              ),
            ),
