我已经在mac中安装了dart（英特尔芯片）：

$ brew info dart                                                                                                                            ‹ruby-2.7.2›

现在我想把dart版本升级到2.18，但是我没有找到新版本的公式：

$ brew install dart@2.18                                                                                                                    ‹ruby-2.7.2›
Warning: No available formula with the name "dart@2.18". Did you mean dart@2.1, dart@2.8, dart@2.13, dart@2.12, dart@2.10, dart@2.2, dart@2.7, dart@2.6, dart@2.5, dart@2.4, dart@2.3, dart@2.9 or dart@2.0?

在macos中安装更高版本的dart是可能的吗？我试着在谷歌上搜索，但仍然没有人谈论这个问题。我应该怎么做来升级dart？我已经尝试了brew升级命令。
