Javascript Dart互操作：如何正确制作包装器？

如何正确制作包装纸？我需要包装此方法：

js:

---

如果这是正确的，我如何在dart代码中运行它？columnDefs中没有这种方法。

您可以使用

js

包中的

js_util

库。以下代码应该可以工作：

import 'package:js/js.dart';
import 'package:js/js_util.dart' as js_util;

@JS()
external List get columnDef;

set suppressFilterButton(bool value) {
  final floatingFilterComponentParams = js_util.getProperty(columnDef[0], 'floatingFilterComponentParams');
  js_util.setProperty(floatingFilterComponentParams, suppressFilterButton, value)
}

@JS('ColumnDef.floatingFilterComponentParams')
//class floatingFilterComponentParams extends ColumnDef {
class floatingFilterComponentParams {
  external set suppressFilterButton(bool value);
}

import 'package:js/js.dart';
import 'package:js/js_util.dart' as js_util;

@JS()
external List get columnDef;

set suppressFilterButton(bool value) {
  final floatingFilterComponentParams = js_util.getProperty(columnDef[0], 'floatingFilterComponentParams');
  js_util.setProperty(floatingFilterComponentParams, suppressFilterButton, value)
}
