The plugin stops working with "Invalid number" issue

[PandaGeek1024]

As you can see it just stops working as below:

$ flutter packages pub run flutter_launcher_icons:main
Android minSdkVersion = 
FormatException: Invalid number (at character 1)

Here is my config:

flutter_icons:
  image_path: "assets/images/icon.png"
  android: true
  ios: true

And my SDK version:

minSdkVersion 21
targetSdkVersion 28

I don't think this is an issue with this package.

Do you know where that FormatException is being throw? Such as the file and line number

[PandaGeek1024]

Somehow after I restarted the mac, it backs on working again.... I have no idea how it is fixed. Will close it anyway.

[PandaGeek1024]

It happens again, now I know why. In the plugin code, it actually loads all text from gradle file and look for the minSdk assignment line for the number. Unfortunately, in my case im use a global variable so it couldn't read the number. Change it back to number solves the problem.

@PandaGeek1024

It is closed but I also meet the problem.

because of in the android/app/build.gradle
it wrote like this.

        minSdkVersion versions.minSdk

I can resolve by replacing it the number.
where versions.minSdk came from?

[shinriyo]

I got lit.

it was customized like this.

in android/versions.gradle

ext {
    versions = [
            compileSdk           : 29,
            minSdk               : 23,
            targetSdk            : 29,

If I have a time, I try to fix the external file supports.

I ran into the same error when I had defined my extension in android/build.gradle:

ext {
       compileSdkVersion   = 29
       targetSdkVersion    = 29
       minSdkVersion       = 23
   }

Passing the numbers directly in android/app/build.gradle worked for me.

Is there a separate open issue for this?

[StalderT]

In my case, I have in build.gradle file :

    defaultConfig {
        applicationId "com.xxxxxxxxxxx"
        // minSdkVersion is determined by Native View.
        minSdkVersion 20
        targetSdkVersion 30
        versionCode flutterVersionCode.toInteger()
        versionName flutterVersionName
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
    }

Removing the line // minSdkVersion is determined by Native View. fix the issue

Please reopen, We need a fix for that because the latest flutter 2.8.0 generates the gradle with variables instead of numbers

[marcobazzani]

I fixed with this PR
master...marcobazzani:patch-1

it's not great but I dunno where to find minSdk so I just handled the exception gracefully and fall back to the already present return 0

Any update on this bug?

I've just created a new project and added the plugin for testing and getting the following error:

flutter pub run flutter_launcher_icons:main

j'ai remplacé :
minSdkVersion flutter.minSdkVersion
targetSdkVersion flutter.targetSdkVersion
par:
minSdkVersion 20
targetSdkVersion 30

et ça marche à merveille

[MariamZekri]

you can define another variable with the minSdkVersion in app.gradle just make sure it is defined above defaultConfig and this a work around , you will have two minSdkVersion variables.
