Use url_launcher to open the url in flutter, but I want to open it in incognito mode, what do I need to do, thanks
I am using an Android device
Case A: If you mean Chrome on Android: It is impossible, even if you are writing native java code: How to open a web page in Google chrome incognito from android app.
Case B: If you mean any browser on Android, actually some browsers does not have such a incognito mode. For those browsers which supports incognito mode, you may try to search for that particular browser.
Actually, why do you want to open incognito? Maybe you can just use the in-app browser package of Flutter, instead of opening an external browser.

I am trying to make a website using flutter and want to test it on a mobile browser. Is there any way to run the project on a mobile browser?
I think you should use your browser Inspector and then use toggle device toolbar to set browser size to your intended mobile size.
Or you can get web output of your website and put it on some server (like Github-pages) and then see your website in a real mobile browser.
But I suggest the first way more.
I'm only targeting Android and iOS for now and the url_launcher plugin only works for default browser.
I have Chrome installing my PWA on Android - once it's installed I'd like to automatically close the browser window it was installed from, and open the PWA (so the user doesn't continue in the browser window, thinking they're using the PWA) - is this possible?
i was looking for a similar solution and have not yet found a way to do that. I try to describe my findings so far:
CLOSING THE BROWSER WINDOW:
as described in this answer window.close() can only be called on windows/tabs that the script opened itself. Some possible workarounds are being discussed there.
OPENING THE PWA RIGHT AFTER INSTALLATION:
Google describes in their WebApk Fundamentals Article it as follows:
When a Progressive Web App is installed on Android, it will register a set of intent filters for all URLs within the scope of the app. When a user clicks on a link that is within the scope of the app, the app will be opened, rather than opening within a browser tab.
I was hoping that would work also right after the installation/Adding to homescreen from the still open browser window.
Based on testing with two Android devices it seems as if at the moment the user has to manually open the PWA from the homescreen once for chrome/android to interpret the scope of the web apps manifest.json as intend to open the page in standalone.
This is sad for even iOS seems to handle that different.
Maybe I am overlooking something in the Google Article? I also do not fully understand androids intent API - so maybe there is some way to still achieve that (?)
Based from this blog post:
When the PWA is installed, it will appear in the home screen, in the
app launcher, in Settings and as any other first-class citizen app in
the OS, including information on battery and space used in the system.
There's a tracking event when the user opens the app from the home screen. That means the user has clicked the app's icon or, on Android with WebAPK support, also clicked on a link pointing to the PWA scope and need to close the browser.
start_url: '/?utm_source=standalone&utm_medium=pwa'
Also, the following script leaves us a boolean stating if the user is currently in a browser (true) or a standalone app mode (false)
var isPWAinBrowser = true;
// replace standalone with fullscreen or minimal-ui according to your manifest
if (matchMedia('(display-mode: standalone)').matches) {
// Android and iOS 11.3+
isPWAinBrowser = false;
} else if ('standalone' in navigator) {
// useful for iOS < 11.3
isPWAinBrowser = !navigator.standalone;
}
I had this problem on Android with Chrome. The change that made the difference is adding "target='_blank'" to the link. It looks like:
window.addEventListener('appinstalled', function(event){
setTimeout(function(){
presentToUser("<a href='https://myhostname.com' target='_blank'>Go to App</a>")
}, 10000)}
});
The ten second timeout is to give Android the time to set up the App on the home page.
I had made that adjustment earlier; possibly I can remove it?
But setting the target was what made this work.
The App opens over the top of Chrome, obscuring it.
So closing the browser is not immediately required but is recommended.
In the new versions of chrome, after installation in android it associate all the links in the "scope" to the PWA application, if you try to open a link in your chrome browser it open directly in the application.
hope that will answer your question
I am examining PWA and Web Components technologies recently. As far as I have learned now Web Components is a new suit of tech,
Custom Elements, Shadow DOM, HTML Templates and HTML imports. Together with those Web Components enabling techs Web App Manifest, Service Workers, and certain performance improvement techniques used to make what is called as Progressive Web Applications.
What I wonder is when one "Adds to Home Screen" an application in a certain web browser what is the browser that opens it when it is launched from its home screen icon? Is it the browser it has been added to home screen from, or it is the default browser of the system no matter which browser it has been added to home screen from, or it is just a generic web view available on the host operating system at the moment like the one used in native web applications?
Lastly, is it possible for a developer coding her/his app to choose one?
Currently, for me, these combinations open a new "Standalone" window
I believe Android/Chrome is the only one that installs a WebApk
All the others are just shortcuts to open your website in that browser without the normal browser navigation items
I know of no options for the developer for how the shortcut opens your PWA
Android 8.10 - Chrome 67
Android 8.10 - Chrome (beta) 68
Android 8.10 - Edge 42
Android 8.10 - Opera 43
iOS 11.4 (simulator) - Safari
As test I created app shortcut of site https://pwa.rocks from browser:
Brave
Firefox
Chrome
and found that there were 3 different shortcut created for each of the browser. Launching each shortcut resulted in opening the respective browser that created it.
I believe there is no way of changing the default browser to launch the app by coding something in the app. I could not find a way of doing that, if someone knows how to do it, I will be interested to know about it
Here is similar question: What browser will PWA (Progressive Web App) use after adding to home screen?
In the WebView that is based on default browser of android my website isn't loading correctly, How can I load it using chrome at least in the case that chrome is installed?
Note that I don't want execute chrome browser I want to embed it inside of the application layout. Any ideas?
I think what you are asking is not possible. The default browser used within the webview is defined within the Android OS so your only option if you wanted to use Chrome is via an intent which would open it externally
