what should I do to change the MACOSX_DEPLOYMENT_TARGET when build flutter macos app

I am building flutter(v3.0.4) macos app in macOS(v12.4 M1 chip) using this command:

~/fvm/versions/3.0.4/bin/flutter build macos --release

shows error like this:

    ➜  macos git:(main) ✗ ~/fvm/versions/3.0.4/bin/flutter build macos --release --no-tree-shake-icons
Changing current working directory to: /Users/xiaoqiangjiang/source/reddwarf/frontend/tik

💪 Building with sound null safety 💪

Building macOS application...

I have already change the Pods and Runner deployment target to 10.11. what should I do to change the MACOSX_DEPLOYMENT_TARGET version? this is the macos podfile:

platform :osx, '10.11'

# CocoaPods analytics sends network stats synchronously affecting flutter build latency.
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', 'ephemeral', '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 Flutter-Generated.xcconfig, then run \"flutter pub get\""
end

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

flutter_macos_podfile_setup

target 'Runner' do
  use_frameworks!
  use_modular_headers!

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

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

this is the Pods macOS deployment config:

I have already tried to clean the build and rebuild the macos app but still could not work as expect.

Solution

  • Went into my macos/Podfile and replaced the post_install method that looked like so…

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

    to look like so instead.

    post_install do |installer|
  installer.pods_project.targets.each do |target|
    flutter_additional_macos_build_settings(target)
    target.build_configurations.each do |config|
      config.build_settings['MACOSX_DEPLOYMENT_TARGET'] = '10.15'
    end
  end
end
