ngx-smart-modal事件不适用于生产版本

Question

我正在使用ngx-smart-modal软件包使用modal。对于开发版本来说，它工作正常，但是对于生产版本而言，它却不起作用，这意味着当aot当时设置为true时，它不起作用

这是我的生产版本配置

"production": {
              "fileReplacements": [
                {
                  "replace": "src/environments/environment.ts",
                  "with": "src/environments/environment.prod.ts"
                }
              ],
              "optimization": true,
              "outputHashing": "all",
              "sourceMap": false,
              "extractCss": true,
              "namedChunks": false,
              "aot": true,
              "extractLicenses": true,
              "vendorChunk": false,
              "buildOptimizer": true,
              "budgets": [
                {
                  "type": "initial",
                  "maximumWarning": "2mb",
                  "maximumError": "5mb"
                }
              ]
            }

这是我的角度配置

Angular CLI: 7.2.3

webpack                           4.28.4

当aot设置为false时，这是我的代码，可以正常工作

// do stuffs when modal has been closed. 
    this.ngxSmartModalService.getModal('modal1').onClose.subscribe((modal: NgxSmartModalComponent) => {
      // do something
       console.log("Modal is closed");
    });
    // do stuffs when modal has been dismissed i.e when the modal is closed clicking in backdrop.
    this.ngxSmartModalService.getModal('modal1').onDismiss.subscribe((modal: NgxSmartModalComponent) => {
      // do something
       console.log("Modal is closed");
    });
    this.ngxSmartModalService.getModal('modal1').onEscape.subscribe((modal: NgxSmartModalComponent) => {
      // do something
       console.log("Modal is closed");
    });

根据上面的代码，预计Modal is closed应该在浏览器的控制台中打印，但是当aot设置为true时，它不会打印日志。
