Firebase Flutter Snippets

This repository holds code snippets used in Flutter documentation on firebase.google.com.

These snippets are part of our documentation and best read in the context of a documentation page rather than used directly.

Each snippet has a "region tag" which is defined by // [START tag] and // [END tag] comments. The code between the tags can be included in our documentation. Keeping the code on GitHub, rather than hard-coded into the HTML of our documentation, allows us to ensure the code is correct and up to date.

Set up / Running Instructions - WIP

• installed flutter, intellij, intellij plugins
• created firebase project, downloaded firebase CLI, installed flutterfirecli
• flutter create firestore-snippets && cd firestore-snippets
• flutterfire-configure

Snippet structure

Note: Most snippets follow this structure, but in some cases multiple snippets are located in a single function. In this case, the function name represents which snippet the function name starts on.

Each Firebase product (that requires Flutter snippets) has its own file located in the dir apps/firestore_snippets/lib/snippets.

Each of these files defines a class called [Firebase Product Name]Snippets. These classes have a separate function for each snippet. These functions follow the naming convention of firebaseDocsPageName_snippetTitle. For example: FirestoreSnippets.getStarted_addData. Each snippet is also wrapped by comments which define the beginning and ending of the snippet, and generally excludes the function names. The code in this region, between the two comments, is the code that appears in the Firebase documentation.

Example:

See translated snippet in the Firebase documentation

  void getStarted_addData() async {
  // [START get_started_add_data_1]
  // Create a new user with a first and last name
  final user = <String, dynamic>{
    "first": "Ada",
    "last": "Lovelace",
    "born": 1815
  };

  // Add a new document with a generated ID
  db.collection("users").add(user).then((DocumentReference doc) =>
      print('DocumentSnapshot added with ID: ${doc.id}'));
  // [END get_started_add_data_1]
}
