Getting a substitution tag by key

public func getTag(withKey key: String) -> String?

All substitution tags will be retrieved by the SDK before starting the first process and will be stored in memory.

Whenever the container app needs a substitution tag value for populating the UI of the custom components, it can request the substitution tag using the method above, providing the key.

For example, substitution tags can be used to localize the content inside an application.

​

Example

​

Localizing the app

The flxLocalize pipe is found in the FlxLocalizationModule.

import { FlxLocalizationModule } from 'flowx-process-renderer';

import { Component } from '@angular/core';

@Component({
  selector: 'app-dummy-component',
  template: ` <h3>{{ "stringToLocalize" | flxLocalize}}</h3>`,

})
export class DummyComponent{
 stringToLocalize: string = `@@localizedString`
}

Strings that need to be localized must have the ’@@’ prefix which the flxLocalize pipe uses to extract and replace the string with a value found in the substitution tags enumeration.

Substitution tags are retrieved when a start process call is first made, and it’s cached on subsequent start process calls.
