If you are trying to display a dialog that has a <code>Consumer</code> (to use <code>ref</code> inside), move your <code>Consumer</code> inside the builder inside the <code>builder</code>:
<code>showDialog</code> is like <code>Navigator.push</code>, you should only call it in <code>onPressed</code>, <code>onTap</code> or <code>initState</code>, not in a <code>build</code> method as you don't control how many times your widget will rebuild.
It doesn't build a widget (like the other widgets), it pushes a new dialog page in the history (like <code>Navigator.push</code>).
<pre class="lang-dart prettyprint-override"><code>// Here you are in a `onPressed` of a button (for example):
showDialog(
 context: context,
 builder: (BuildContext context) {
 return Consumer(builder: (context, ref, _) {
 return AlertDialog(
 content: unrelatedfunc(),
 actions: [
 TextButton(
 child: const Text('Share'),
 onPressed: () {
 submit();
 _TextFieldController.clear();
 Navigator.of(context).pop();
 },
 ),
 ],
 );
 });
 },
);
</code></pre>
If you need to use <code>ref</code> in the same method that is displaying the dialog (calling <code>showDialog</code>) (let's say the <code>onPressed</code> of a button), you can wrap the button with the <code>Consumer</code>:
<pre class="lang-dart prettyprint-override"><code>Consumer(
 builder: (context, ref, _) {
 return TextButton(
 child: Text('My button'),
 onPressed: () {
 // You can use `ref` here.
 showDialog(
 context: context,
 builder: (context) {
 return AlertDialog(/* ... */);
 },
 );
 },
 );
 },
);
</code></pre>

blocks|key|3930597|text|使用NavigatorState().push。当您试图转到包含showDialog而不是showDialog的屏幕时|type|unstyled|depth|inlineStyleRanges|entityRanges|data|3930598|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

Use NavigatorState().push... when you were trying to go to the screen that contains showDialog instead of Navigator.of(....).push...

I'm not sure what i'm missing i have this simple method with a Consumer class that returns a Dialog, but the problem is the following
The return type 'Future' isn't a 'Widget', as required by the closure's context.
it points to the line indicated below.
<pre><code> func() {
 Consumer(builder: (context, ref, _) {
 return showDialog( // &lt;- [ERROR HERE]
 context: context,
 builder: (BuildContext context) {
 return AlertDialog(
 content: unrelatedfunc(),
 actions: [
 TextButton(
 child: const Text('Share'),
 onPressed: () {
 submit();
 _TextFieldController.clear();
 Navigator.of(context).pop();
 })
 ],
 );
 });
 });
 }

</code></pre>
i'm not sure why but i have been investigating and i haven't seen an example like this

Riverpod / Flutter Use showDialog inside Consumer Class

我不知道我缺少了什么--我有一个返回对话框的使用者类的简单方法，但是问题是返回类型'Future‘不是'Widget'，这是闭包上下文所要求的。它指向下面所示的线。  func() {    Consumer(builder: (context, ref, _) {      return showDialog(   ...
