I’m showing an AlertDialog on my App, but when I click on no/cancel then AlertDialog doesn’t dismiss, it keep popping the route where I came from. I’ve used Navigator.of(context).pop(); and Navigator.pop(context, false); but both are not working.

Solution

To Dismiss an AlertDialog Navigator.of(context).pop(); works but in my case below code worked.

Navigator.of(context, rootNavigator: true).pop('dialog');

That’s All.

1. Delete .idea folder.
2. Create a new temporary Flutter project with the same name.
3. Copy from the project to your existing project these 2 missing files:

• [project_name].iml
• android/[project_name]_android.iml

4. Open Android Studio and the problem should be gone.

To avoid it in the future, make sure .iml files are not excluded in the gitignore. There is a Github issue on this topic.

I have implemented firebase phone Auth in my flutter app but whenever i fill phone no. and click on send otp then it opens a RECAPTCHA verification url in browser by default. I don’t want to show it.

See the below screenshot of popup.

Solution

Follow the below Steps :-

Step 1 :- Go to Google Cloud Console, enable the Android Device Check API for your project ( Select the same project which you have created in firebase for flutter App. ). The default Firebase API Key will be used, and needs to be allowed to access the DeviceCheck API.

Step 2 :- If you haven’t added SHA-256 fingerprint in firebase then add it too.

For more information, you can also check Google SafetyNet API for checking Google Play Services installation in device at the time of Phone Authentication.

I’m Calling An API to update my data and I got this error, the Error Says,

E/flutter (32582): type 'int' is not a subtype of type 'String' in type cast

Solution

Step 1: use "content-type": "application/json" in header

Step 2: encode your body like jsonEncode( {"param1": 10, "param2":20,"param3": "abc","param4": true})

Example Code Like

headers: {
      "content-type": "application/json",
    },
    body:jsonEncode( {
      "qualificationId": 10,
      "year":2001,

I’m Calling An API and getting response in Variable Data ($data). When data is coming then there is no Error but when I’m getting null as response then getting this error Unhandled Exception: NoSuchMethodError: The getter ‘isEmpty’ was called on null.

When I am using the below code then it is throwing me an error:

Solution

That is because $data returns null, So I’ve Used

if(data?.isEmpty ?? true)

? prevents an error if the previous part of the expression results in null and ?? true results in true if the previous part of the expression is null and therefore treats == null and isEmpty the same for the if(...) check.

Now My Code is working Fine.

I’ve connected my flutter app to firebase by adding SHA1 key ( How to Get SHA-1 key in Android Studio for Firebase. ) and package name in firebase console, and also downloaded and provided google-service.json in my flutter app at android/app. But when i run app its Showing an error that i’ve not provided google-service.json file in my app. The Error Says –

E/flutter (15568): [ERROR:flutter/lib/ui/ui_dart_state.cc(166)] Unhandled Exception: [core/not-initialized] Firebase has not been correctly initialized. Have you added the "google-services.json" file to the project? 
E/flutter (15568): 

Solution

After hours of struggle, I am able to figure out the solution.

1. First, add the ‘google-services.json‘ plugin as a dependency inside of the android/build.gradle file:

 buildscript {
      dependencies {
        // ... other dependencies
        classpath 'com.google.gms:google-services:4.3.3'
      }
    }

2. Lastly, execute the plugin by adding the following underneath the line apply plugin:
add after ‘com.android.application’, within the /android/app/build.gradle file:

apply plugin: 'com.google.gms.google-services'

That’s All.
