StackOverflowError 由我的自定义 bottom-sheet 小部件抛出

Question

当我尝试在我的底页小部件上设置值时，抛出以下错误：

Exception caught by widgets library ═══════════════════════════════════ The following WhosebugError was thrown building BSheetWidget(dirty, dependencies: [MediaQuery], state: _BSheetWidgetState#759dc): Stack Overflow

The relevant error-causing widget was BSheetWidget lib\…\client\clientscreen_view.dart:874 When the exception was thrown, this was the stack #0 Driver.carReference package:taxi_app/…/models/driver.dart:29 #1 Driver.carReference package:taxi_app/…/models/driver.dart:29 #2 Driver.carReference package:taxi_app/…/models/driver.dart:29 #3 Driver.carReference package:taxi_app/…/models/driver.dart:29 #4 Driver.carReference package:taxi_app/…/models/driver.dart:29 ... ════════════════════════════════════════════════════════════════════════════════ Reloaded 1 of 2190 libraries in 2 987ms.

我发现问题出在这里：

child: Container(
                      child: Column(
                        mainAxisAlignment: MainAxisAlignment.spaceAround,
                        children: [
                          Column(
                            mainAxisAlignment: MainAxisAlignment.center,
                            children: [
                              Text('vehicule model'),
                            ],
                          ),
                          Text(widget.fullData.driver.carReference != null ? widget.fullData.driver.carReference.toString() : '', style: TextStyle(color: ThemeUtils.bluePlus,fontSize: 18)), //
                        ],
                      ),
                    ),

但我发现当我尝试更改文本时：

 Text(widget.fullData.driver.carReference != null ? widget.fullData.driver.carReference.toString() : '', style: TextStyle(color: ThemeUtils.bluePlus,fontSize: 18)),

有效：

我的模特：

@override
  Driver clone(Map<String, dynamic> map) => Driver()..fromJson(map);

  static const String carNameKey = 'carName';
  static const String carReferenceKey = 'carReference';
  static const String carSerieKey = 'carSerie';
  static const String carImageKey = 'carImage';

  String get carName => get<String>(carNameKey);
  String get carReference => get<String>(carReference);
  String get carSerie => get<String>(carSerie);
  ParseFile get carImage => get<ParseFile>(carImageKey);

  set carName(String value) => set<String>(carNameKey, value);
  set carReference(String value) => set<String>(carReferenceKey, value);
  set carSerie(String value) => set<String>(carSerieKey, value);
  set carImage(ParseFile value) => set<ParseFile>(carImageKey, value);

Answer 1

解决方法是将我的setter修改为

  String get carReference => get<String>(carReferenceKey);
  String get carSerie => get<String>(carSerieKey);
