To find out the consumer’s choice, you possibly can incorporate a settings panel inside your add-on. This panel would supply a toggle or choice for the consumer to pick their most well-liked theme. The chosen choice is then saved in UserProperties.
When the add-on hundreds, you possibly can retrieve the consumer’s choice from UserProperties and dynamically apply the suitable CSS types. This usually entails including or eradicating CSS courses or loading separate CSS information, much like the method used for net apps. Contemplate the next Google Apps Script snippet:
perform onOpen(e) {
var ui = DocumentApp.getUi();
ui.createMenu('My Add-on')
.addItem('Settings', 'openSettingsSidebar')
.addToUi();
}
perform openSettingsSidebar() {
var userProperties = PropertiesService.getUserProperties();
var darkModeEnabled = userProperties.getProperty('darkModeEnabled');
var template = HtmlService.createTemplateFromFile('SettingsSidebar');
template.darkModeEnabled = darkModeEnabled === 'true';
var html = template.consider().setTitle('My Add-on Settings');
DocumentApp.getUi().showSidebar(html);
}
Server-Facet Issues
For each net apps and add-ons, it’s vital to think about the server-side implications of implementing darkish mode. The consumer’s theme choice, detected or set on the client-side, must be communicated to the server-side Google Apps Script code in order that it may possibly generate HTML content material dynamically primarily based on the chosen theme. This may be achieved by way of numerous mechanisms, akin to passing the theme choice as a parameter in a URL or submitting it as a part of a type.
On the server-side, you should utilize conditional statements to generate completely different HTML content material relying on the theme choice.
