My Code is not working. Do not opening email via this code. Their shows a null error.
Add this in AndroidManifest.xml just above of application
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.QUERY_ALL_PACKAGES" />
<queries>
<intent>
<action android:name="android.intent.action.VIEW" />
<category android:name="android.intent.category.BROWSABLE" />
<data android:scheme="https" />
</intent>
<!-- If your app opens https URLs -->
<intent>
<action android:name="android.intent.action.VIEW" />
<data android:scheme="http" />
</intent>
<!-- If your app opens https URLs -->
<intent>
<action android:name="android.intent.action.VIEW" />
<data android:scheme="https" />
</intent>
</queries>
In launch you are converting it to a string whereas it would require a uri to be launched. Remove .toString from the launch method
launch(emailLaunchUri);

I'm currently working on deep links on Flutter. I managed to have almost everything working, except for this strange behaviour on Android 12 only. (iOS working also fine).
If I set a custom scheme for the deep links in the manifest, then Android 12 will make the https links to not open the app, but I can see the domain is actually just disabled if I go in "Applications -> Default Applications -> Link opening -> My App -> Web links", and enabling it solves the issue. If I don't set a custom scheme, then the domain is enabled on build.
It's currently only been tested on local debug builds if this matters.
As I said, beside this on Android 12, everything works as intended. I put this configuration :
<meta-data android:name="flutter_deeplinking_enabled" android:value="true" />
<intent-filter android:autoVerify="true">
<action android:name="android.intent.action.VIEW" />
<category android:name="android.intent.category.DEFAULT" />
<category android:name="android.intent.category.BROWSABLE" />
<data android:host="my.domain.fr" />
<data android:scheme="https" />
<data android:scheme="http" />
<data android:scheme="custom" /> <------ Removing this makes a difference
</intent-filter>
I've set the assetlinks with the correct domain :
[{
"relation": ["delegate_permission/common.handle_all_urls"],
"target": {
"namespace": "android_app",
"package_name": "my.app.bundle",
"sha256_cert_fingerprints": ["AV:ER:YN:IC:ES:HA:25:6X"]
}
}]
From what I've understood, the links being enabled when not using the custom scheme are a good clue it works as intended, and the file is also said to be working fine with online testing tools.
The similar working method on iOS works without any issue.
I'm expecting the web links https://my.domain.fr to open in the app, but the option to do so is disabled in the app settings by default ONLY IF I use a custom scheme alongside.
you have to separate the intent-filter for the custom scheme.
from this
<intent-filter android:autoVerify="true">
<action android:name="android.intent.action.VIEW" />
<category android:name="android.intent.category.DEFAULT" />
<category android:name="android.intent.category.BROWSABLE" />
<data android:host="my.domain.fr" />
<data android:scheme="https" />
<data android:scheme="http" />
<data android:scheme="custom" /> <------ Removing this makes a difference
</intent-filter>
to this
<intent-filter android:autoVerify="true" android:label="testHttpDeepLink">
<action android:name="android.intent.action.VIEW" />
<category android:name="android.intent.category.DEFAULT" />
<category android:name="android.intent.category.BROWSABLE" />
<data android:host="my.domain.fr" />
<data android:scheme="https" />
<data android:scheme="http" />
</intent-filter>
<intent-filter android:autoVerify="true" android:label="testAppDeepLink">
<action android:name="android.intent.action.VIEW" />
<category android:name="android.intent.category.DEFAULT" />
<category android:name="android.intent.category.BROWSABLE" />
<data android:scheme="custom" />
</intent-filter>
Flutter ,My Launcher is not working With Link Widget of Url Launcher.
final websiteUri = Uri.parse('https://flutter.dev');
Link(
uri: websiteUri,
target: LinkTarget.blank,
builder: (context, openLink) => TextButton(
onPressed: openLink,
child: Text(websiteUri.toString()),
),
)
use launchUrlString from the url_launcher package instead:
final websiteUri = 'https://flutter.dev';
onpressed:launchUrlString(websiteUri);
I just updated my AndroidManifest.xml , according to: https://pub.dev/packages/url_launcher#android and https://developer.android.com/training/package-visibility/use-cases#check-browser-available
and finally i add thi to AndroidManifest.xml like:
<queries>
<!-- If your app checks for SMS support -->
<intent>
<action android:name="android.intent.action.VIEW" />
<data android:scheme="sms" />
</intent>
<!-- If your app checks for call support -->
<intent>
<action android:name="android.intent.action.VIEW" />
<data android:scheme="tel" />
</intent>
<!-- Place inside the <queries> element. -->
<intent>
<action android:name="android.intent.action.VIEW" />
<category android:name="android.intent.category.BROWSABLE" />
<data android:scheme="https" />
</intent>
</queries>
It worked Perfectly no issues 🫡
ElevatedButton(
onPressed: () async {
const url ='https://www.facebook.com';
if (await canLaunch(url)) {
await launch(url,forceWebView: true,enableJavaScript: true);
} else {
// can't launch url
}
},
);
I/UrlLauncher( 7566): component name for https://www.facebook.com is null
Add the queries for each platform, follow the documentation in this link URL Launcher API Reference
iOS
Add any URL schemes passed to canLaunchUrl as LSApplicationQueriesSchemes entries in your Info.plist file.
<key>LSApplicationQueriesSchemes</key>
<array>
<string>https</string>
<string>http</string>
</array>
Android
Starting from API 30 Android requires package visibility configuration in your AndroidManifest.xml otherwise canLaunchUrl will return false. A element must be added to your manifest as a child of the root element.
<queries>
<!-- If your app opens https URLs -->
<intent>
<action android:name="android.intent.action.VIEW" />
<data android:scheme="https" />
</intent>
<!-- If your app makes calls -->
<intent>
<action android:name="android.intent.action.DIAL" />
<data android:scheme="tel" />
</intent>
<!-- If your sends SMS messages -->
<intent>
<action android:name="android.intent.action.SENDTO" />
<data android:scheme="smsto" />
</intent>
<!-- If your app sends emails -->

This works for me!
I am trying to integrate Branch,io in my flutter project via flutter_branch_sdk. I have followed this tutorial https://www.youtube.com/watch?v=H3ihnIrtw_Q. I can generate link and it redirects and opens the app but not to specific screen of the app. However, when I run validateSdkIntegration method. it print this.
3. Verifying application package name ...

i wanted to know how to make my app as a default pdf viewer. Please see the screenshot below :
So when a user clicks on the pdf file the flutter app should open it. and should be visible in the list of pdf openers.
check out receive_sharing_intent
and add below code in your manifest
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>
<uses-permission android:name="android.permission.MANAGE_EXTERNAL_STORAGE"
