Error adding Flutter web-view plugin in version 1.20.4

Question

I would like to use flutter-web plugin in my app. However, I am getting the following SDK error when I add it to my YAML file. I just upgraded to 1.20.4

How do I fix this error?

The current Flutter SDK version is 1.20.4.

Because app depends on webview_flutter >=1.0.0 which requires Flutter SDK version >=1.22.0 <2.0.0, version solving failed. pub get failed (1; Because app depends on webview_flutter >=1.0.0 which requires Flutter SDK version >=1.22.0 <2.0.0, version solving failed.)

Doctor summary (to see all details, run flutter doctor -v): [✓] Flutter (Channel stable, 1.20.4, on Mac OS X 10.15.6 19G2021, locale en-US)

[✓] Android toolchain - develop for Android devices (Android SDK version 28.0.3) [✓] Xcode - develop for iOS and macOS (Xcode 12.0) [✓] Android Studio (version 3.6) [✓] VS Code (version 1.49.2) [✓] Connected device (1 available)

• No issues found!

This is the info in my pubspec.yaml file

environment: sdk: ">=2.2.2 <3.0.0"

webview_flutter package need minSdkVersion 19 so you have to change the app level gradle

android {
    defaultConfig {
        // Required by the Flutter WebView plugin.
        minSdkVersion 19
    }
  }

after upgrade your flutter using flutter upgrade

and then import webview_flutter In your pubspec.yaml file webview_flutter: ^1.0.0 because webview_flutter is stable in flutter 1.22 stable release.

Thanks. so, if I change to minSdkVersion to 19 (currently 16). Would that mean that android user whose phone <=16 will not be able to use the app

yes, @user2570135 user below 19 is not able to use it.

I was facing the same problem but I did not know the path of that build.gradle so I found it after spending some time.

You have to edit the build.gradle file. In a flutter project, it is found at the path ./android/app/build.gradle.

The parameter that needs to be changed is, of course, minSdkVersion 16, bumping it up to what you need (in this case 19).

defaultConfig {
    // TODO: Specify your own unique Application ID (https://developer.android.com/studio/build/application-id.html).
    applicationId "com.example.web_view_example"
    minSdkVersion 19 //This is what you need to change.
    targetSdkVersion 31
    versionCode flutterVersionCode.toInteger()
    versionName flutterVersionName
}
