Flutter 中在showDialog里的Provider不更新

这样写是没有更新的

import 'package:flutter/material.dart';
import 'package:provider/provider.dart';

void showDialog1(BuildContext context) {
  showDialog(
    context: context,
    builder: (ctx) {
      return Text("${ctx.watch().text1}");
    },
  );
}

包一层StatefulBuilder就行了

import 'package:flutter/material.dart';
import 'package:provider/provider.dart';

void showDialog2(BuildContext context) {
  showDialog(
    context: context,
    builder: (ctx) {
      return StatefulBuilder(
        builder: (BuildContext context, void Function(void Function()) setState) {
          return Text("${ctx.watch().text1}");
        },
      );
    },
  );
}
