Intégration Firebase avec Flutter Android ne fonctionne pas

J'ai essayé de mettre en œuvre toutes les choses requises pour Android, mais bien que l'application fonctionne sur iOS, elle ne fonctionne pas sur Android. Quelqu'un peut-il s'il vous plaît me dire ce qui ne va pas et comment résoudre ce problème.

Faire flutter pub cache repair pour résoudre les problèmes avec vos packages/plugins Flutter dans le répertoire de cache (qui pourraient parfois re-télécharger chaque package dans le cache).

Effacer le ~/.pub-cache le répertoire fonctionnera également. Dans mon système, ce répertoire situé à C:\Users\BLiyanage\AppData\Roaming\Pub\Cache\hosted (Cet emplacement peut différer pour vous).

Pour IOS .pub-cache existe à: Users/someuser/.pub-cache/hosted/pub.dartlang.org

Lire la suite ici pour résoudre des problèmes similaires à celui-ci. Et similaire téléscripteur .

Modifiez settings.gradle comme suit:

include ':app'

def flutterProjectRoot = rootProject.projectDir.parentFile.toPath()

def plugins = new Properties()
def pluginsFile = new File(flutterProjectRoot.toFile(), '.flutter-plugins')
if (pluginsFile.exists()) {
    pluginsFile.withReader('UTF-8') { reader -> plugins.load(reader) }
}

plugins.each { name, path ->
    def pluginDirectory = flutterProjectRoot.resolve(path).resolve('Android').toFile()
    include ":$name"
    project(":$name").projectDir = pluginDirectory
}
