dealCol method
Implementation
List<Widget> dealCol(double allWidth) {
List<Widget> list = <Widget>[];
// 根据 span 不超过 24 处理为二维数组
List doubleList = _dealToDouble();
for (var j = 0; j < doubleList.length; j++) {
List itemList = doubleList[j];
double spanWidth = _calcSpanWidth(itemList.length, allWidth);
for (var i = 0; i < itemList.length; i++) {
Widget child = itemList[i].getChild();
Map props = itemList[i].getProps();
list.add(EasyCol(
child: child,
span: props['span'],
offset: props['offset'],
spanWidth: spanWidth,
));
}
}
return list;
}
