<div class =“post-text”itemprop =“text”> <P> 您需要更改_buildRow（）和_buildRowList（）方法： </p> <pre> <code> Widget _buildRow(Groups parkingGroup, BuildContext context) { return Container( padding: const EdgeInsets.all(16.0), child: Column( // As you expect multiple lines you need a column not a row children: _buildRowList(parkingGroup), ), ); } List<Widget> _buildRowList(Groups parkingGroup) { List<Widget> lines = []; // this will hold Rows according to available lines for (var line in parkingGroup.lines) { List<Widget> placesForLine = [] // this will hold the places for each line for (var placeLine in line.places) { placesForLine.add(_buildPlace(placeLine)); } lines.add(Row(children: placesForLine)); } return lines; } </code> </pre> </DIV>
