Aether Core for Flutter

Application framework for flutter development.    

Settings files

Create the following 3 files:

assets\system\settings.json
assets\system\settings.staging.json
assets\system\settings.debug.json

Flow logic in sequence:

1. The system will first load the settings.json.
2. If in staging mode, load settings.staging.json and override any existing settings.
3. If in debug mode, load settings.debug.json and override any existing settings.

Example

{
    "ApiBaseUrl": "https://viqcommunity.com",
    "ApiKey": "<Api Key>",
    "ApiConnectTimeoutInSec": 15,
    "GooglePlayURL": "https://play.google.com/store/apps/details?id=com.viqcore.community_live",
    "AppleAppStoreURL": "https://apps.apple.com/my/app/viqcore-community/id1499329657",
    "HuaweiAppGalleryURL": "https://appgallery.cloud.huawei.com/marketshare/app/C102024395?locale=en_GB&source=appshare&subsource=C102024395"
}

Building App Service

Before RunApp, build the AppService via AppBuilder.

final builder = AppBuilder();

// Customize the credential actions
builder.useCredentialActions(
    CredentialActions(
        signIn: (request) => CredentialManager.login(request),
        signOut: () => CredentialManager.logout(),
        refreshCredential: () => CredentialManager.loginRefresh(),
        getCredential: () => CredentialManager.refreshCredential()),
  );

// Customize dialog settings
builder.useDialogSettings(
  const DialogSettings(
    buttonTitleColor: MainTheme,
  ),
);

// Customize snackbar settings
builder.useSnackbarSettings(
  const SnackbarSettings(
      errorIcon: Icon(AppIcons.snackbarError, color: Colors.red),
      infoIcon: Icon(AppIcons.snackbarInfo, color: MainTheme)),
);

// Build the app service
await builder.build(appName: 'VIQ Community Admin');

Dialog, Snackbar and Progress indicator

// Dialog
App.dialog({String? title, 
            String? description, 
            String? cancelTitle, 
            Color? cancelTitleColor, 
            String? buttonTitle, 
            Color? buttonTitleColor,  
            bool barrierDismissible = false, 
            DialogPlatform? dialogPlatform})
            
App.confirm(String question, 
            {String? title, 
             String? buttonTitle, 
             String? cancelButtonTitle})

// Notification
App.info(String info, {String? title})
App.error(dynamic error, {String? title})

// Progress indicator
App.showProgressIndicator({String? status})
App.dismissProgressIndicator()

Entity

class Company extends Entity {
  late final Field<DateTime> name = field('name');
  late final Field<DateTime> time = field('time');
  late final Field<int> capacity = field('capacity');
  late final Field<double> kpi = field('kpi');
  late final ListField<Machine> machines = fieldList('machines');
  late final Field<Settings> settings = field('settings');
  late final Field<PlanQuality> planQuality = field('planQuality');

  Company() {
    print('Company constructor');
    capacity.computed(
      bindings: [machines],
      compute: () => machines.fold(0, (p, e) => p! + e.capacity()),
    );
    machines.register(() => Machine());
    settings.register(() => Settings(), auto: true);
    print('End of Company constructor');
  }
}

class Machine extends Entity {
  late final Field<String> name = field('name');
  late final Field<int> capacity = field('capacity');
}

class Settings extends Entity {
  late final Field<int> minCapacity =
      field('minCapacity', defaultValue: 10);
}

class PlanQuality extends Entity {}

API Connect

Quick REST API Access

final result = await '/api/login'.api(body: request.data).post(
        timeout: Duration(seconds: 5),
        headers: {"AppToken": request["appToken"]});

By default it will connect via the App.connect. You may override it for external api.

final response = await 'https://oauth2.googleapis.com/token'
          .api(body: {
            'code': code,
            'client_id': clientID,
            'client_secret': clientSecret,
            'redirect_uri': redirectUri,
            'grant_type': 'authorization_code',
          })
          .external() // Indicate this is an external API
          .post();

Quick GraphQL API Access

 'community'
        .gql([...data.fragment, 'location'.gql(Location().fragment)],
            params: {'id': communityId})
        .query()
        .then((response) {
          if (response.hasError) {
            App.error(response.errorText);
            return;
          }
          if (response.isOk) {
            data.load(response.body);
          }
        });
