这里存在：

我的问题控制器

Rx<GitlabIssue> selectedIssue = new GitlabIssue().obs;
RxList<GitlabIssue> issues = <GitlabIssue>[].obs;


void changeIssueState(GitlabIssueState state) async {
var stateValue = _getGitLabIssueStateValue(state);
bool isInternet = await Utils().isInternet();
if (isInternet) {
  var resp = await _issueProvider.changeGitlabIssueState(
      projectId, selectedIssue.value.iid, stateValue);

  if (resp.statusCode == 200) {
    Get.snackbar(
      'Issue state changed',
      'Issue is $stateValue',
    );
    var issueIndex = issues.indexOf(selectedIssue.value);
    selectedIssue.value.state =
        selectedIssue.value.state == 'opened' ? 'closed' : 'opened';
    issues[issueIndex] = selectedIssue.value;

    gitLabIssueBox.put(projectId, issues);
  } else
    Get.snackbar(
        'Issue state not changed', 'Issue state was not correctly changed');
} else
  print('No connectivity');
}

我的观点

 Widget _getButtonStatus() {
return Obx(() {
  Color stateColor = _issueController.selectedIssue.value.state == 'closed'
      ? Colors.green
      : Colors.red;
  return OutlinedButton(
    onPressed: () {
      _issueController.selectedIssue.value.state == 'closed'
          ? _issueController.changeIssueState(GitlabIssueState.reopen)
          : _issueController.changeIssueState(GitlabIssueState.close);
    },
    style: OutlinedButton.styleFrom(
      //primary: Colors.white,
      //backgroundColor: Colors.teal,
      side: BorderSide(color: stateColor, width: 1),
    ),
    child: Obx(
      () => Text(
        _issueController.selectedIssue.value.state == 'closed'
            ? 'Reopen issue'
            : 'Close issue',
        style: TextStyle(color: stateColor),
      ),
    ),
  );
});
}

我更新了 selectedIssue.obs 的值，并将小部件放入 Obx() => 函数中。

我不知道为什么我的小部件不重绘。

奇怪的是，我的 onPressed 函数表现正确；该按钮保持不变，但如果我再次单击它，我的问题状态会正确更改。

请帮我 ！！:D
