Add closeAllIfPossible() method

[em-yhoshino]

What is this?

I have added closeAllIfPossible(), which closes all launched SFSafariViewControllers via flutter_custom_tabs, to launcher.

Before this PR

Once the app launched a SFSafariViewController via flutter_custom_tabs, it could not be closed until the user closed it. Therefore, the SFSafariViewController was masking the deep link transition.

After this PR

The app can close all SFSafariViewController at any time.
It is especially useful before deep link transitions.

How to use

Like this,

import 'package:flutter_custom_tabs/flutter_custom_tabs.dart' as custom_tabs;

await custom_tabs.launch(uriString);

// When deeplink is invoked
await custom_tabs.closeAllIfPossible();
await transition(deeplink);

It avoids occuring a transition behind a SFSafariViewController that is not closed by user.

Android and web

In Android and web, empty operations have been implemented because there is no proper way to close customTabs.
At least, Android doesn't require it in case of deep link scenario.
This is because customTabs are automatically closed when app returns from background.

The CI failed due to the dependency specification.
How can I solve it?

I think that we need to push the contents on this branch to pub.dev for the CI to be succeeded.

Thank you so much for this, exactly what I needed. I'm also using deep links to hide the custom tabs on Android, works perfectly. For iOS there seems to be no other way than what you have done here to close the custom tabs (I tried all kinds of javascript & deep link shenanigans).

I had to download it locally and edit the pubspec files to get the dependencies to work like you said - not sure how to correctly fix it though so it'd work in the CI. Just wanted to thank you for this valuable feature.

Hello @em-yhoshino,
I really need your implementation of closeAllIfPossible() since in iOS, custom tab doesn't close after deep link and no way to close it manually so I'm trying to use your forked plugin version by putting this lines in my pubspec.yaml:

  flutter_custom_tabs:
    git:
      url: https://github.com/em-yhoshino/flutter_custom_tabs.git
      ref: master

Actually flutter pub get is returning this error:

Could not find a file named "pubspec.yaml" in https://github.com/em-yhoshino/flutter_custom_tabs.git eff797dda32aaa9bbc88af9e384f86e74f5a50d4.
pub get failed (1; Could not find a file named "pubspec.yaml" in https://github.com/em-yhoshino/flutter_custom_tabs.git eff797dda32aaa9bbc88af9e384f86e74f5a50d4.)
exit code 1

What am i doing wrong? Is it possible to test it or am i supposed to wait for @droibit to merge into a new officiale version?
Thanks for letting me know.
Regards
Angelo

Thank you for the PR!
I apologize for not replying for a long time.

This plugin has not been maintained for a long time
so don't worry about the error on CI.

I will fix the workflows later.

Thank you so much for coming back to this project! Looking forward to being able to use this version (not the fork) again once it's live on pub.dev :)
