flutter_open_whatsapp's Issues

This plugin is not important!

you can use url_launcher, and device_apps to do everything you need...
i don't use this plugin i faced it randomly, i wanted to help people because it sounds like no body updates this plugin a long time

who want to open WA only, just use this line of code
device_apps:
DeviceApps.openApp('com.whatsapp');

who want to open it with text message use this line of code:
url_launcher:
launch('https://api.whatsapp.com/send/?phone=(phone number here without +)&text=(you message here)&app_absent=1');

does not speficify a SWIFT VERSION

Can't run Pod install. Message below:

How to send the message without press the whatsapp "send"

Builds are failing due to forced casts - iOS

Hi, I have been trying to use this package for a Flutter iOS app, but I am getting the following warnings that do not let the app build successfully:

/.pub-cache/hosted/pub.dartlang.org/flutter_open_whatsapp-0.1.2/ios/Classes/SwiftFlutterOpenWhatsappPlugin.swift:30:58: warning: forced cast from 'NSURL?' to 'URL' only unwraps and bridges; did you mean to use '!' with 'as'?
if UIApplication.shared.canOpenURL(whatsAppUrl as! URL) {
~~~~~~~~~~~ ^~~ ~~~
!as

/.pub-cache/hosted/pub.dartlang.org/flutter_open_whatsapp-0.1.2/ios/Classes/SwiftFlutterOpenWhatsappPlugin.swift:31:58: warning: forced cast from 'NSURL?' to 'URL' only unwraps and bridges; did you mean to use '!' with 'as'?
UIApplication.shared.openURL(whatsAppUrl as! URL)
~~~~~~~~~~~ ^~~ ~~~
!as

I am trying to run the app from Android Studio 3.6.3 and building the iOS version with XCode 11.4.1.

What could the problem be? Thanks for your help.

Country code

@rohit1814 when use url_launcher to call a phone number I do something like this:

 final url = "tel:${myInvestment['contact']['phone']}";
                    if (await canLaunch(url)) {
                      await launch(url);
                    } else {
                      throw 'Could not launch $url';
                    }

That would call to the exact phone number I have saved, that means that it would not include extra country codes.

Doing something like this:
FlutterOpenWhatsapp.sendSingleMessage(666666666, "");
will open a [phone] and it'd work. But it have +34 on my contact it would add another +34 and it would fail.

Also I cannot have another number from a different country because it adds a wront country code.

I think we should have this logic independently on our sides but not on this package

International phone number cant send message to indian number.

On Android it does not encode the message correctly (it only trims)

This is a problem when the message contains a link with ?. Then everything after and including the ? is cut off.

Bug: Complete message not being sent.

Test message: Hello # World
Message shown in whatsapp: Hello

I found the error was because the plugin was not encoding the message in URI format, due to this it escaped at "#". It is a critical bug and I think the library should encode the message and then send it.

Would be happy to contribute :)

Android Error: Cannot run with sound null safety, because the following dependencies don't support null safety:

• package:flutter_open_whatsapp

Can we use it to ask to open between WA and WB

Hi, I'm trying to use this in an app. How can I make it to ask to select between WhatsApp or WhatsApp Business.

Can you also send images?

I would like to be able to send images to people who are not in my contact list. Would that be possible with this plugin?

null safety

Null safety will be available soon ?
