flutter dart 上對象的參數值

Question

我是 flutter 的新手，我試圖從對象列表中獲取一個對象，我使用了以下內容。

setProject (int idProject) {
var selectedProject =
this._projectsUser.where ((project) => project ['id'] == idProject);
// print ('selectedProject $ {selectedProject}');
this._project = selectedProject;
}

其中變量是：

List _projectsUser = [];
Object _project = {};

但是當我想獲取對象參數的值時，我收到以下錯誤： The operator '[]' isn't defined for the class 'Object'.

Answer 1

測試這個

 setProject (int idProject) {
    var selectedProject = this._projectsUser.where ((project) => project ['id'] == idProject).toList()[0];
    this._project = selectedProject;
    print(selectedProject);
  }

  List _projectsUser = [{'id':1, 'name':'nothing'},{'id':1, 'name':'nothing2'},{'id':1, 'name':'nothing2'}];
  Object _project = {};
