Google Charts API Wrapper

A library to make it easy to use Google's visualization api

This package was matched against the version released on April 30, 2015 (Version 42).


You can use the api almost as you would do in the javascript version.

  1. Include <script type="text/javascript" src=""></script> in the head section of your HTML code.

  2. Use the load method of the Chart you want to use to load the required package(s) asynchronously. Afterwards you can go ahead and write your code.

      LineChart.load().then((_) {
     var chart = new LineChart(...);
     var data = new DataTable(...);
  3. When using the API itself you can use Chart.load() to only load the API without any packages.

Implemented wrappers

  • All Charts are implemented, included the corecharts and all other charts.
  • Material charts (Line, Bar/Column, Scatter)
  • Query API
  • Formatters
  • Static methods like arrayToDataTable, drawChart and drawToolbar
  • Events

Dart Code

import 'package:google_visualization_api/google_visualization_api.dart';

void main() {
  PieChart.load().then((_) {
    var data = arrayToDataTable([
      ['Task', 'Hours per Day'],
      ['Work', 11],
      ['Eat', 2],
      ['Commute', 2],
      ['Watch TV', 2],
      ['Sleep', 7]

    var options = {'title': 'My Daily Activities'};

    var chart = new PieChart(document.getElementById('piechart'));

    chart.draw(data, options);

Issues and suggestions

Fix lib/src/visualization/annotation_chart.dart.

Analysis of lib/src/visualization/annotation_chart.dart failed with 1 error:

line 8 col 3: Invalid override. The type of 'AnnotationChart.draw' ('(dynamic, [Map<dynamic, dynamic>, dynamic]) → void') isn't a subtype of 'Chart.draw' ('(dynamic, [dynamic]) → void').

Support Dart 2 in pubspec.yaml.

The SDK constraint in pubspec.yaml doesn't allow the Dart 2.0.0 release. For information about upgrading it to be Dart 2 compatible, please see

Package is too old.

The package was released more than two years ago.

The description is too short.

Add more detail about the package, what it does and what is its target use case. Try to write at least 60 characters.

Package is pre-v1 release.

While there is nothing inherently wrong with versions of 0.*.*, it usually means that the author is still experimenting with the general direction of the API.

Format lib/base.dart.

Run dartfmt to format lib/base.dart.

Maintain an example.

None of the files in your example/ directory matches a known example patterns. Common file name patterns include: main.dart, example.dart or you could also use google_charts.dart.
