flutter - Error: The method 'ignore' isn't defined for the class 'Future<state>' in flutter build</state>

问题描述

Today when I compile my flutter project, the OS is macOS Big Sur, shows error like this:

../../../.pub-cache/hosted/mirrors.tuna.tsinghua.edu.cn%2547dart-pub/riverpod-1.0.0-dev.10/lib/src/async_value_converters.dart:223:39: Error: The method 'ignore' isn't defined for the class 'Future<State>'.
 - 'Future' is from 'dart:async'.
Try correcting the name to the name of an existing method, or defining a method named 'ignore'.
            loadingCompleter!.future..ignore(),
                                      ^^^^^^

I am using the riverpod dependencies like this:

hooks_riverpod: ^1.0.0-dev.6

This problem was the first time to occurred. what should I do to fix this problem? This is the flutter environment info:

$ ~/apps/flutter/bin/flutter doctor                                                                                                         ‹ruby-2.7.2›
