There are 13 plugin kits built in the latest open source version of UME. Developer could create custom plugin kits, and integrate them into UME. Visit Develop plugin kits for UME for more details.

Please see Plugins from community to make your ume stronger.

Quick Start #

All packages whose names are prefixed with ume_kit_ are function plug-ins of UME, and users can access them according to demand

  1. Edit pubspec.yaml, and add dependencies.

    Compatible with Flutter 3 since version 1.0.0.

    dev_dependencies:
  ume: ^2.0.0
  ume_kit_ui: ^2.0.0
  ume_kit_device: ^2.0.0
  ume_kit_perf: ^2.0.0
  ume_kit_show_code: ^2.0.0
  ume_kit_console: ^2.0.0
  ume_kit_dio: ^2.0.0

  2. Run flutter pub get

  3. Import packages

    import 'package:ume/ume.dart'; // UME framework
import 'package:ume_kit_ui/ume_kit_ui.dart'; // UI kits
import 'package:ume_kit_perf/ume_kit_perf.dart'; // Performance kits
import 'package:ume_kit_show_code/ume_kit_show_code.dart'; // Show Code
import 'package:ume_kit_device/ume_kit_device.dart'; // Device info
import 'package:ume_kit_console/ume_kit_console.dart'; // Show debugPrint
import 'package:ume_kit_dio/ume_kit_dio.dart'; // Dio Inspector

  4. Edit main method of your app, register plugin kits and initial UME

    void main() {
  if (kDebugMode) {
    PluginManager.instance                                 // Register plugin kits
      ..register(WidgetInfoInspector())
      ..register(WidgetDetailInspector())
      ..register(ColorSucker())
      ..register(AlignRuler())
      ..register(ColorPicker())                            // New feature
      ..register(TouchIndicator())                         // New feature
      ..register(Performance())
      ..register(ShowCode())
      ..register(MemoryInfoPage())
      ..register(CpuInfoPage())
      ..register(DeviceInfoPanel())
      ..register(Console())
      ..register(DioInspector(dio: dio));                  // Pass in your Dio instance

    runApp(UMEWidget(child: MyApp(), enable: true));
  } else {
    runApp(MyApp());
  }
}

  5. flutter run for running or flutter build apk --debug、flutter build ios --debug for building productions.

Some functions rely on VM Service, and additional parameters need to be added for local operation to ensure that it can connect to the VM Service.

Flutter 2.0.x, 2.2.x and other versions run on real devices, flutter run needs to add the --disable-dds parameter. After Pull Request #80900 merging, --disable-dds was renamed to --no-dds.

IMPORTANT #

From 0.1.1/0.2.1 version，we don't need set useRootNavigator: false. The following section only applies to versions before version 0.1.1/0.2.1 .

Since UME manages the routing stack at the top level, methods such as showDialog use rootNavigator to pop up by default, therefore must pass in the parameter useRootNavigator: false in showDialog, showGeneralDialog and other 'show dialog' methods to avoid navigator errors.

showDialog(
  context: context,
  builder: (ctx) => AlertDialog(
        title: const Text('Dialog'),
        actions: <Widget>[
          TextButton(
              onPressed: () => Navigator.pop(context),
              child: const Text('OK'))
        ],
      ),
  useRootNavigator: false); // <===== It's very IMPORTANT!

Develop plugin kits for UME #

UME plugins are located in the ./kits directory, and each one is a package. You can refer to the example in ./custom_plugin_example about this chapter.

  1. Run flutter create -t package custom_plugin to create your custom plugin kit, it could be package or plugin.

  2. Edit pubspec.yaml of the custom plugin kit to add UME framework dependency.

    dependencies:
  ume: ^2.0.0

  3. Create the class of the plugin kit which should implement Pluggable.

    import 'package:ume/ume.dart';

class CustomPlugin implements Pluggable {
  CustomPlugin({Key key});

  @override
  Widget buildWidget(BuildContext context) => Container(
    color: Colors.white
    width: 100,
    height: 100,
    child: Center(
      child: Text('Custom Plugin')
    ),
  ); // The panel of the plugin kit

  @override
  String get name => 'CustomPlugin'; // The name of the plugin kit

  @override
  String get displayName => 'CustomPlugin';

  @override
  void onTrigger() {} // Call when tap the icon of plugin kit

  @override
  ImageProvider<Object> get iconImageProvider => NetworkImage('url'); // The icon image of the plugin kit
}

  4. Use your custom plugin kit in project

    1. Edit pubspec.yaml of host app project to add custom_plugin dependency.

      dev_dependencies:
  custom_plugin:
    path: path/to/custom_plugin

    2. Run flutter pub get

    3. Import package

      import 'package:custom_plugin/custom_plugin.dart';

  5. Edit main method of your app, register your custom_plugin plugin kit

    if (kDebugMode) {
  PluginManager.instance
    ..register(CustomPlugin());
  runApp(
    UMEWidget(
      child: MyApp(),
      enable: true
    )
  );
} else {
  runApp(MyApp());
}

  6. Run your app

Access the nested widget debug kits quickly #

We introduce the PluggableWithNestedWidget from 0.3.0. It is used to insert nested Widgets in the Widget tree and quickly access embedded kits with nested widget.

For more details, see ./kits/ume_kit_ui/lib/components/color_picker/color_picker.dart and ./kits/ume_kit_ui/lib/components/touch_indicator/touch_indicator.dart.

The key steps are as follows:

  1. The class of your plugin should implement PluggableWithNestedWidget.
  2. Implements Widget buildNestedWidget(Widget child). Handling the nested widgets and returning the new Widget.

How to use UME in Release/Profile mode #

Once you use ume in Release/Profile mode, you agree that you will bear the relevant risks by yourself.

The maintainer of ume does not assume any responsibility for the accident caused by this.

We recommend not to use it in Release/Profile mode for the following reasons:

  1. VM Service is not available in these environments, so some functions are not available
  2. In this environment, developers need to isolate the app distribution channels by themselves to avoid submitting relevant debugging code to the production environment

In order to use in Release/Profile mode, the details that need to be adjusted in the normal access process:

  1. In pubspec.yaml, ume and plugins should be write below dependencies rather than dev_dependencies.
  2. Don't put the code which call PluginManager.instance.register() and UMEWidget(child: App()) into conditionals which represent debug mode. (Such as kDebugMode)
  3. Ensure the above details, run flutter clean and flutter pub get, then build your app.

About the third-party open-source project dependencies #

  • The TouchIndicator use the pub touch_indicator, the ColorPicker use the pub cyclop.
  • We fork the package cyclop and modify some code meet our functional needs. We should depend cyclop by pub version after the PR being merged.
