Getting started

First, you need to contact 2GIS technical support to get a new key. Be sure to specify the appId of the application for which the key will be generated. Add the resulting key file dgissdk.key to assets.

To begin working with the SDK, call the initialize() method of a DGis object and specify the application context:

import 'package:dgis_mobile_sdk_map/dgis.dart' as sdk;

class SomeApp : StatelessWidget() {
    final sdkContext = sdk.DGis.initialize();
}

Note that you cannot create more than one Context instance.

Additionally, you can specify logging settings (LogOptions) and HTTP client settings (HttpOptions) such as request timeout:

import 'package:dgis_mobile_sdk_map/dgis.dart' as sdk;

class SomeApp : StatelessWidget() {

  final sdkContext = sdk.DGis.initialize(
    logOptions: const sdk.LogOptions(
      customLogLevel: sdk.LogLevel.verbose,
      logLevel: sdk.LogLevel.verbose,
    ),
    httpOptions: const sdk.HttpOptions(
      timeout: Duration(seconds: 5),
    ),
  );
}

To override some SDK operation settings, use a file in the VendorConfig format. The file is passed during SDK initialization.

There are several ways to create an instance of the VendorConfig class:

  • VendorConfigFromAsset - locate the file in the assets directory of the application source code and specify the file name in the constructor.
  • VendorConfigFromFile - locate the file on the device file system and specify the absolute path to it.
  • VendorConfigFromString - pass a string with the contents of the JSON file to the constructor.

The created VendorConfig instance is passed to the DGis.initialize() method with the vendorConfig parameter.
