EasyUser #

• Easyuser package helps managing user account in Firebase.

Setup #

Storage Security Rules #

• Add the following security rules on storage.

rules_version = '2';
service firebase.storage {
  match /b/{bucket}/o {
    match /{allPaths=**} {
      allow read, write: if false;
    }
    match /easyuser/{userId}/{allPaths=**} {
      allow read: if true;
      allow write: if request.auth.uid == userId;
    }
  }
}

User document #

• The user document is stored on firestore as /users/{uid}

• How to create user document. See EasyUser::create.

• To update the user document direcly, you can use below. But it is not recommended. Instead, use EasyUser.instance.update(field: xxx, value: xxx)

await EasyUser.instance.doc.update({
    'photoUrl': FieldValue.delete(),
});

Admin #

• Admin can be set as the security rules.

Upload #

• All the upload of files and images are handled in easy user package.
• Images are stored in /users/{uid}/...

Widgets #

UserDoc #

• One of the best widgets that you can use all the time is UserDoc. It has three builders.
  • builder will build widgets if the user has logged in and has user document.
  • documentNotExistBuilder will build a widget. You may return an empty widget while create the user's document. Then, it the builder will be called and you can display the widget for login.
  • notLoggedBuilder will build widgets for not logged in users. You can registeration or login widgets.

UserDoc(
  builder: (user, doc) {
    return Column(
      children: [
        Text("Hello, ${doc.displayName}! (uid: ${user.uid})"),
        Text(doc.toString()),
        ElevatedButton(
            onPressed: EasyUser.instance.signOut, child: const Text('Logout'))
      ],
    );
  },
  notLoggedInBuilder: () {
    final auth = FirebaseAuth.instance;
    final emailController = TextEditingController();
    final passwordController = TextEditingController();
    return Column(
      children: [
        const Text("Please, login"),
        TextField(
          controller: emailController,
