Flutter onTextScaleFactorChanged 错误？

Question

我最近更新了 Flutter 和我的包，现在我遇到了这个我以前没有遇到的错误。我已经重新启动了 IntelliJ，并且正在对我的 FlutterDoctor 进行所有检查。

NoSuchMethodError: Class 'Window' has no instance setter 'onTextScaleFactorChanged='. Receiver: Instance of 'Window' Tried calling: onTextScaleFactorChanged=Closure: () => void from Function 'handleTextScaleFactorChanged':.

* 添加了 textAlign 代码 *

class NumberOnesPageState extends State<NumberOnesPage> {List names = new List();
    List numbers = new List();
    List ids = new List();
    List vidImages = new List();


    void _handleJson(value) {


      Map myMap = value; //store each map
      var titles = myMap.values;
      for (var items in titles){
        names.add(items['vidTitle']);
        numbers.add(items['Value']);
        ids.add(items['vidId']);
        vidImages.add(items['vidImage']);

      }

    }

                                          ),
                                        ),
                                      );
                                  }
                                });
                          }))
                ],
              )),
            ));
      }
    }

这是我的 textAlign 代码。它在升级之前没有给出任何错误，并且按预期生成了居中的文本。不确定是否是导致错误的代码。

我已经注释掉了我所有的 textAlign 函数。没有任何工作。它有效地将我锁定在我的代码库之外。

Answer 1

对我有用的是：

• 卸载应用程序
• 运行flutter upgrade
• 运行flutter doctor
• 通过命令行运行flutter run。 （IntelliJ 可能有效，但我已经在命令行中）

我不确定最初是什么导致了问题，但这似乎为我解决了问题。
