Fixing Flutter iOS App: Unable to Get Intent Global URLs for Share Extension

Fixing Flutter iOS App: Unable to Get Intent Global URLs Share Extension

In this article, we will discuss a common issue faced by Flutter developers when building an iOS app with a share extension. Specifically, we will cover the problem of not being able to get the global URLs when trying to share a website.

Background and Context

When building a Flutter iOS app with a share extension, it is common to encounter issues related to the app's ability to receive and handle global URLs. These URLs are the uniform resource locators (URLs) that are used to identify resources on the internet, such as websites. The share extension is a component of the app that allows users to share content from other apps with your app. In order for your app to receive the shared content, it must be able to handle the global URLs sent by the share extension.

In some cases, you may find that your Flutter iOS app is unable to receive the global URLs sent by the share extension. This can prevent your app from properly handling the shared content and negatively impact the user experience. In the following sections, we will discuss the steps you can take to resolve this issue.

Understanding the Problem

The first step in resolving the problem of not being able to get global URLs in your Flutter iOS app's share extension is to understand the root cause of the issue. In many cases, this issue occurs because the app's Info.plist file is not properly configured to handle the global URLs.

The Info.plist file is an XML property list file that contains important information about your app. This includes information about the app's capabilities, such as the ability to handle global URLs. In order for your app to receive the global URLs sent by the share extension, you must properly configure the Info.plist file to include the necessary keys and values.

Fixing the Problem

To fix the problem of not being able to get global URLs in your Flutter iOS app's share extension, follow these steps:

1. Open the Info.plist file for your app's share extension.

2. Add the following keys and values to the Info.plist file:

   {
       "CFBundleURLTypes" : [
           {
               "CFBundleURLSchemes" : [ "myapp" ]
           }
       ],
       "NSExtension" : {
           "NSExtensionAttributes" : {
               "NSExtensionActivationSupportsFileWithMaxSize" : 1048576
           },
           "NSExtensionMainStoryboard" : "MainInterface",
           "NSExtensionPointIdentifier" : "com.apple.share-services"
       }
   }

   In the above code snippet, replace "myapp" with the URL scheme for your app. This is the part of the URL that comes before the colon (:). For example, if your app's URL is "myapp://example.com", the URL scheme would be "myapp".

3. Save the Info.plist file and rebuild your app.

By adding the necessary keys and values to the Info.plist file, you are telling the app that it is capable of handling global URLs. This will allow the app to receive the global URLs sent by the share extension and properly handle the shared content.
