I would like to use a modify version of stripe_ios library in flutter_stripe library to include a missing functionality I added.
for that I downloaded both libraries and copy them inside a packages directory of my flutter app.
then inside pubspec.yaml I declared the library like that:
flutter_stripe:
path: packages/stripe
then in flutter_stripe library folder I edited stripe_ios/ios/stripe_ios.podspec to make Stripe library reference point to my modified version:
Pod::Spec.new do |s|
s.name = 'stripe_ios'
s.version = '0.0.1'
s.summary = 'A new flutter plugin project.'
s.description = <<-DESC
A new flutter plugin project.
DESC
s.homepage = 'http://example.com'
s.license = { :file => '../LICENSE' }
s.author = { 'Your Company' => 'email#example.com' }
s.source = { :path => '.' }
s.source_files = 'Classes/**/*'
s.dependency 'Flutter'
s.dependency 'Stripe'
s.subspec 'Stripe' do |ss|
ss.source_files = '../../library/StripeIos/Stripe'
end
s.platform = :ios, '11.0'
# Flutter.framework does not contain a i386 slice.
s.pod_target_xcconfig = { 'DEFINES_MODULE' => 'YES', 'EXCLUDED_ARCHS[sdk=iphonesimulator*]' => 'i386' }
s.swift_version = '5.0'
end
But it seems it's not working correctly and when I do pod install from ios folder it seems to download version 21.13.0 of Stripe ios library instead.
any idea how to achieve this correctly ?
I am trying to include .a files on the iOS side of the plugin. Below is my file structure.
Now when I try to add .a files via vendored_libraries on podspec, pod install is successfully completed. And when I compile the code, I get Library Not Found -lAccuraFace
I tried to add the .a file on the Link Binary With Libraries section on the build phase on the Pod target. It's still the same, how can I define the podspec in such a way that the .a file is included and linked automatically.
Here is my podspec file for the plugin
Pod::Spec.new do |s|
s.name = 'accuraemirates'
s.version = '0.0.1'
s.summary = 'A new Flutter plugin.'

s.dependency 'Flutter'
s.public_header_files = 'Classes/*{.h}'
s.private_header_files = 'Classes/CodeScan/**/*{.h,.cpp,.a}'

s.swift_version = '5.0'

Is it not possible to add/link .a libraries from podspec file on a flutter plugin.
Finally found the issue..
Pod::Spec.new do |s|
# other obvious values
s.source_files = 'Classes//*{.h,.a,.swift,.mm,.m,.hpp}'
s.resources = 'Resources//'
s.static_framework = true
s.public_header_files = "Classes/VideoCamera/VideoCameraWrapperDelegate.h", "Classes/VideoCamera/VideoCameraWrapper.h",'Classes/.h',
s.private_header_files = 'Classes/CodeScan//{.h,.cpp,.hpp}'
s.platform = :ios, '8.0'
s.preserve_paths = 'opencv2.framework', 'Classes/Framework/.a'
s.xcconfig = {
# here on LDFLAG, I had to set -l and then the library name (without lib prefix although the file name has it).
'OTHER_LDFLAGS' => '-framework opencv2 -lc++ -lAccuraFace -lAccuraEmirate -lDocRecog -lz',
'USER_HEADER_SEARCH_PATHS' => '"${PROJECT_DIR}/.."/',
"LIBRARY_SEARCH_PATHS" => '"${PROJECT_DIR}/.."/*',
}
s.vendored_frameworks = 'opencv2.framework' # Various framworks you need
# Here the name of the library can include lib as the file name has it too.
s.vendored_libraries = 'AccuraFace','libAccuraEmirate','libDocRecog'
end
Notice two values here OTHER_LDFLAGS and vendored_libraries. Although I have same file, they need names with and without lib prefix. Weird but worked.
You definitely CAN add .a libraries, try to check the following configuration path
TARGETS->Build Settings->Search Paths-> Library Search Paths
Right there, add path where .a library was located.
Here is a valid path configuration demo:
==========================================================================
UPDATE
For flutter plugin
As for ship as flutter plugin ,file with .a suffix is actually static library, here is a snippet for how to do it in a .podspec file:
s.subspec 'Core' do |sc|
sc.ios.library = 'z'
sc.frameworks = 'SystemConfiguration', 'QuartzCore', 'CoreText', 'WebKit'
sc.source_files = 'AppboyKit/headers/AppboyKitLibrary/*.h', 'AppboyKit/ABKIdentifierForAdvertisingProvider.m', 'AppboyKit/ABKModalWebViewController.m', 'AppboyKit/ABKNoConnectionLocalization.m', 'AppboyKit/ABKLocationManagerProvider.m'
sc.resource = 'AppboyKit/Appboy.bundle'
sc.vendored_libraries = 'AppboyKit/libAppboyKitLibrary.a'
sc.weak_framework = 'CoreTelephony', 'Social', 'Accounts', 'AdSupport', 'UserNotifications'
end
Pay attention to line start with sc.vendored_libraries there.Here is the complete source.
ios framework into flutter_plugin
import your Famework or library in both path => Flutter_Plugin/example/ios and Flutter_Plugin/ios .
IN Flutter_plugin/ios/flutter_plugin.podspec file
s.preserve_paths = 'YOUR_FRAMEWORK.framework'
s.xcconfig = { 'OTHER_LDFLAGS' => '-framework YOUR_FRAMEWORK' }
s.ios.vendored_frameworks = 'YOUR_FRAMEWORK.framework'
s.ios.vendored_libraries = 'YOUR_FRAMEWORK'
make your framework embeded and signin in xcode(Flutter_Plugin/example/ios).
!sometimes in DerivedData/.../debug_iphone/flutter_plugin.framework - its not there so make that Flutter_plugin.framework move to that debug_iphone folder , it inside the flutter_plugin folder.
I am trying to develop a Flutter plugin for the Tapkey Mobile SDK.
I managed to add their SDK by modifying the podspec of the plugin and the Podfile of the example:
tapkey.podspec:
Pod::Spec.new do |s|
s.name = 'tapkey'
s.version = '0.0.1'
s.summary = 'A tapkey flutter plugin'
s.description = <<-DESC

s.homepage = 'http://example.com'
s.license = { :file => '../LICENSE' }
s.author = { 'Your Company' => 'email#example.com' }
s.source = { :path => '.' }
s.source_files = 'Classes/**/*'
s.dependency 'Flutter'
s.platform = :ios, '9.0'
s.dependency 'TapkeyMobileLib', '~> 2.5.10.0'
s.static_framework = true
# Flutter.framework does not contain a i386 slice. Only x86_64 simulators are supported.
s.pod_target_xcconfig = { 'DEFINES_MODULE' => 'YES', 'VALID_ARCHS[sdk=iphonesimulator*]' => 'x86_64' }
s.swift_version = '5.0'
end
Podfile:
platform :ios, '9.0'
source 'https://github.com/tapkey/TapkeyCocoaPods'
source 'https://github.com/CocoaPods/Specs.git'
# unmodified Podfile

I have looked at several similar GitHub issues, but could not solve the problem.
I am trying to develop a custom Flutter plugin for iOS.
The customer has shared a Vendor-specific private SDK (Not available in Cocoapods repo) for interacting with external hardware. SDK is in *.framework format.
So I created a new plugin. Inside the plugin, I want to add the SDK dependencies in .podspec file from a local path. How to add this dependency? Is it the right approach or do we have any other option to resolve this problem? Kindly help me.
I was able to resolve this issue by providing all vendor-specific frameworks as s.vendored_frameworks in the podspec configuration of the plugin.
s.vendored_frameworks = 'x1.framework','x2.framework','x3.framework',
Pod::Spec.new do |s|
s.name = 'ble'
s.version = '0.0.1'
s.summary = 'A new flutter plugin project.'
s.description = <<-DESC

DESC
s.homepage = 'http://example.com'
s.license = { :file => '../LICENSE' }
s.author = { 'Your Company' => 'email#example.com' }
s.source = { :path => '.' }
s.source_files = 'Classes/**/*'
s.public_header_files = 'Classes/**/*.h'
s.ios.deployment_target = '10.0'
s.requires_arc = true
s.ios.frameworks = 'Foundation', 'CoreTelephony', 'Security', 'CoreLocation', 'CoreBluetooth', 'CoreMotion', 'UIKit', 'SystemConfiguration', 'LocalAuthentication', 'CoreML'
s.dependency 'Flutter'
s.vendored_frameworks = 'SeosMobileKeysSDK.framework','BerTlv.framework','CocoaLumberjack.framework','JSONModel.framework','Mixpanel.framework'
end
All framework libraries are placed in the plugin folder itself
Summary:
I am building a Flutter Plugin to be used for multiple projects I am developing. I have no experience writing custom platform-specific code.
I am having trouble importing SDK library for IOS *.Framework and *-Resources.bundle to my plugin.

Also, I've tried cleaning and re-building the app but with no success and tried cleaning and re-building the example app but with no success

You've mangled your Podspec file. There should only be one section starting Pod::Spec.new do |s|.... If you want to try the approach in the linked Github issue, your Podspec file should look like this:
Pod::Spec.new do |s|
s.name = 'plugin_name'
s.version = '0.0.1'
s.summary = 'A new flutter plugin project.'
s.description = <<-DESC
A new flutter plugin project.
DESC
s.homepage = 'http://example.com'
s.license = { :file => '../LICENSE' }
s.author = { 'Your Company' => 'email#example.com' }
s.source = { :path => '.' }
s.source_files = 'Classes/**/*'
s.public_header_files = 'Classes/**/*.h'
s.dependency 'Flutter'
s.ios.deployment_target = '9.0'
s.preserve_paths = 'IOSFLUTTERSDK.framework'
s.xcconfig = { 'OTHER_LDFLAGS' => '-framework IOSFLUTTERSDK' }
s.vendored_frameworks = 'IOSFLUTTERSDK.framework'
s.resource_bundle = { 'IOSFLUTTERSDK-Resources' => './*' }
end
However, I've tried this before with no success - I needed to link everything manually via Xcode by opening the project:
open example/ios/Runner.xcworksapce
Click on the "Runner" project at the top, and click on the "Build Phases" item on the right hand side (if "Build Phases" doesn't show, make sure the folder icon on the left is selected, and you've clicked the Runner Target in the middle panel, not the Runner Project).
Find the "Link Binary with Libraries" panel, and click the "+" button:
Select your .framework file and click "Done". Repeat the same under "Embed Frameworks".
I'm not 100% sure, but I think you can do the same under "Copy Bundle Resources".
