My app uses a webview to show my terms and conditions. I make use of the "webview_flutter" package to do that. When I install my app via "flutter run --release", everything works fine and my website is perfectly loaded. When I submit my app to google play in production mode, I get an error when trying to open my webview. Any idea what could cause that error?
I double checked pretty much everything. Error occurs only when installed on my Android devices via google play, but everything works fine when installed via USB cable.
WebView(initialUrl: 'https://xyz.abc/terms')
Expected: Webview should load
Error instead:

What am I missing?
Please include a code snippet of what you are trying to do
In my understanding of your stackTrace you are trying to call list on a null object like this:
final UserData userData = someObjectHere;
function login(UserData userData){
//The problem is that userData might be null which causes your issue
String email = userData[]("Email");
}
You're solution might be to use null aware operators or to manually check whether the object you're calling a method on is not null.
String email = userData?.[]("Email");
or
if(userData != null) String email = userData?.[]("Email");

Thank You in advance.
I am writing a flutter app and every time I run it I get this overwhelming amount of input and I don't know what it means
It happens with every app I run and I don't know why and haven't found information about this
I would share some code but I don't think this has to do with any specific code that I run because it happens with any app.
however, I will include an example of such output

this app does print some text intentionally but all of those errors are weird and confusing
I don't expect to get all this output and think it indicates a problem I don't understand
EDIT: since you asked for it, the code is on github now.
This error is due to the internet connection if the connection is slow or if you are trying to get some data from the api via internet and you are not connected to the internet than this error can occur. The same error occurred in my app also so I reconnected to the internet service and the error was removed so you can also try this.
hope this may help.
I resolved it by adding internet permission and usesCleartextTraffic in android manifest.
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.testapp">
<uses-permission android:name="android.permission.INTERNET" />
<application
android:label="Test App"
android:usesCleartextTraffic="true" <!-- THIS LINE -->
android:icon="#mipmap/ic_launcher">
<activity
android:name=".MainActivity"
android:launchMode="singleTop"
android:theme="#style/LaunchTheme">

I am using flutter_bloc & bloc package to manage state.
In child page i am initialize bloc & while back parent page dispose the bloc object.
When i comes back immediately on parent page that time bloc throw error Unhandled Exception: Bad state: Cannot add new events after calling close because on child page on load i am calling api in bloc. which trigger state after completed api. At that time already bloc object disposed.

So how handle these when bloc already disposed ?
Use common bloc for parent and child.
Create/Initialise bloc in parent when calling child do as following:
`BlocProvider.value( value: BlocProvider.of<BlocA>(context), child: ScreenA(), );`
By writing above you will keep alive the bloc from dispose,
Then you can simply access bloc in child as following:
BlocProvider.of<BlocA>(context)
Just don't dispose it in child,
And then, when you go back to parent from child your bloc won't get disposed and it will only dispose when parent destroy or dispose.
Everything is written there in readme:
