Flutter必须初始化const变量'IconData'

Question

我正在尝试在项目中使用Flutter Icons，并在下载字体和dart类后将它们放入项目中，但是对于dart类，却出现此错误

The const variable 'IconData' must be initialized

MyFlutterApp类：

class MyFlutterApp {
  MyFlutterApp._();

  static const _kFontFam = 'MyFlutterApp';

  static const IconData 3d_rotation = const IconData(0xe800, fontFamily: _kFontFam);
  static const IconData ac_unit = const IconData(0xe801, fontFamily: _kFontFam);
  static const IconData access_alarm = const IconData(0xe802, fontFamily: _kFontFam);
}

我该如何解决这个问题？

Answer 1

变量名称不能以数字开头。更改为：

  static const IconData three_d_rotation = const IconData(0xe800, fontFamily: _kFontFam);
