Flutter.h 未找到错误

Question

几天前我已经失去了为 iOS 构建 Flutter 应用程序的能力。我将我的 iPad 更新到 11.4，这迫使我将 xCode 更新到 9.4，而且我认为 Flutter 也有一个新版本。在我无限的智慧中，我更新了它们，现在无法再测试我的项目了。

随着最后期限的临近，我正在寻找有关如何再次行动的建议。我对 Apple 产品不太熟悉，所以还不太了解 xCode 等。

这是一个全新的“FLUTTER CREATE testproject”项目，没有对其进行任何更改。

Answer 1

1. flutter run [new project] 然后将 iOS 文件夹替换为已存在的项目。 （您需要备份现有项目的 iOS 文件夹。）

2. 将现有项目中的 ios/Runner 替换为新的 iOS 文件夹。

3. Xcode 设置与现有项目相同。

如果出现iOS版本问题，修改Podfile。

deployment_target = '11.0'
        post_install do |installer|
        installer.generated_projects.each do |project|
            project.targets.each do |target|
                target.build_configurations.each do |config|
                    config.build_settings['IPHONEOS_DEPLOYMENT_TARGET'] = deployment_target
                end
            end
            project.build_configurations.each do |config|
                config.build_settings['IPHONEOS_DEPLOYMENT_TARGET'] = deployment_target
            end
        end
    end

4. 然后，cd ios，pod install。

5. 颤动运行。

Answer 2

对于任何来这里的人来说都是 2021

用这个替换你的 pod 文件

platform :ios, '12.0'

ENV['COCOAPODS_DISABLE_STATS'] = 'true'

project 'Runner', {
  'Debug' => :debug,
  'Profile' => :release,
  'Release' => :release,
}

def flutter_root
  generated_xcode_build_settings_path = File.expand_path(File.join('..', 'Flutter', 'Generated.xcconfig'), __FILE__)
  unless File.exist?(generated_xcode_build_settings_path)
    raise "#{generated_xcode_build_settings_path} must exist. If you're running pod install manually, make sure flutter pub get is executed first"
  end

  File.foreach(generated_xcode_build_settings_path) do |line|
    matches = line.match(/FLUTTER_ROOT\=(.*)/)
    return matches[1].strip if matches
  end
  raise "FLUTTER_ROOT not found in #{generated_xcode_build_settings_path}. Try deleting Generated.xcconfig, then run flutter pub get"
end

require File.expand_path(File.join('packages', 'flutter_tools', 'bin', 'podhelper'), flutter_root)

flutter_ios_podfile_setup

def flutter_install_ios_plugin_pods(ios_application_path = nil)
  ios_application_path ||= File.dirname(defined_in_file.realpath) if self.respond_to?(:defined_in_file)
  raise 'Could not find iOS application path' unless ios_application_path

  symlink_dir = File.expand_path('.symlinks', ios_application_path)
  system('rm', '-rf', symlink_dir) # Avoid the complication of dependencies like FileUtils.

  symlink_plugins_dir = File.expand_path('plugins', symlink_dir)
  system('mkdir', '-p', symlink_plugins_dir)

  plugins_file = File.join(ios_application_path, '..', '.flutter-plugins-dependencies')
  plugin_pods = flutter_parse_plugins_file(plugins_file)
  plugin_pods.each do |plugin_hash|
    plugin_name = plugin_hash['name']
    plugin_path = plugin_hash['path']
    if (plugin_name && plugin_path)
      symlink = File.join(symlink_plugins_dir, plugin_name)
      File.symlink(plugin_path, symlink)

      if plugin_name == 'flutter_ffmpeg'
          pod 'flutter_ffmpeg/full-lts', :path => File.join('.symlinks', 'plugins', plugin_name, 'ios')
      else
          pod plugin_name, :path => File.join('.symlinks', 'plugins', plugin_name, 'ios')
      end
    end
  end
end

target 'Runner' do
  use_frameworks!
  use_modular_headers!

  flutter_install_all_ios_pods File.dirname(File.realpath(__FILE__))
end

post_install do |installer|
  installer.pods_project.targets.each do |target|
    flutter_additional_ios_build_settings(target)
  end
end

然后运行

flutter pub get
cd ios
pod install

编辑

如果它不起作用，那么

pod update
flutter clean
flutter run

Answer 3

这样做

$rm ios/Flutter/Flutter.podspec
$flutter clean

然后运行

flutter pub get

和

pod install

Answer 4

对我有用的是改变：

#include "Flutter.h"

到

#include <Flutter/Flutter.h>

Answer 5

我猜这个问题是由中断 cocoapods 安装引起的。这是修复：

• 从您的项目中删除 ios/Flutter/Flutter.framework
• 在 ios 目录中运行pod install。应该生成Flutter.framework，包括Headers/Flutter.h文件
• 运行构建。现在应该一切正常

虽然切换到不同的 Flutter 可能会奏效，但它并不能真正解决缓存损坏的问题。请记住，Flutter 的 master 和 beta 分支不适合生产版本。

Answer 6

当我尝试在我的颤振项目中添加一个分享按钮时，我遇到了这个问题。

我通过以下步骤解决它：

1. 检查您的pubspec.yaml 文件。
2. 您应该确定您的 pod 文件和 cocoapods。为此，您应该在终端中按照以下步骤操作：Cannot Install Cocoapods - No podfile found in the project directory

Answer 7

我整天都在寻找这个问题的答案，终于找到了一个有效的修复程序，在你的终端中运行它：

颤抖干净

颤动运行

我认为这只是一个尚未进入主频道的颤振错误/不兼容。
