When i create 'flutter project' in Android Studio with flutter-i18n plugin connected there's no lib/generated/i18n.dart created. So no working mechanizm for internazionalization as described in doc.

my settings are:

It's all because of Android Studio-3.3.1 bug... As soon as i downgraded subj to 3.2 all became correct.

Solution 2: Cristian Madrid

Just check if the file: misc.xml exists inside of .idea folder.

<?xml version="1.0" encoding="UTF-8"?>
<project version="4">
  <component name="ExternalStorageConfigurationManager" enabled="true" />
  <component name="NodePackageJsonFileManager">
    <packageJsonPaths />
  <component name="ProjectRootManager" version="2" languageLevel="JDK_1_8" project-jdk-name="1.8" project-jdk-type="JavaSDK">
    <output url="file://$PROJECT_DIR$/out" />
