我当然是编程和扑动的新手。我正在尝试使用firebase pod来验证我的应用程序中的用户。 Android和它的“pubspec”就像一个魅力，但我不能让ios pod工作。每当我尝试使用其中一个已安装的pod时，我会收到以下错误：
MissingPluginException（找不到通道插件上的方法signInWithEmailAndPassword的实现插件.flutter.io / firebase_auth）
The 'podfile' and the 'podfile.lock' look like this:
# Uncomment this line to define a global platform for your project
# platform :ios, '9.0'
# CocoaPods analytics sends network stats synchronously affecting
flutter build latency.
ENV['COCOAPODS_DISABLE_STATS'] = 'true'

file_abs_path = File.expand_path(file)
if !File.exists? file_abs_path
return [];
end
pods_ary = []
skip_line_start_symbols = ["#", "/"]
File.foreach(file_abs_path) { |line|
next if skip_line_start_symbols.any? { |symbol| line =~ /^\s*#
{symbol}/ }
plugin = line.split(pattern=separator)
if plugin.length == 2
podname = plugin[0].strip()
path = plugin[1].strip()
podpath = File.expand_path("#{path}", file_abs_path)

end
}
return pods_ary

首先尝试 flutter软件包获得 然后在 pods文件夹中打开终端。
执行命令pod安装或pod更新
然后打开 xcodeproject 文件并 clean 项目，然后构建
答案 1 :(得分：0)
你有： 1.在pubspec.yaml中包含firebase auth的依赖项，然后尝试“flutter packages get＆＃39;和＆＃39;颤动包升级＆＃39; 2.更新您的xcode并安装可选工具
答案 2 :(得分：0)
尝试步骤：
打开终端然后cd到项目
flutter clean
flutter pub get
