loadJsFromAssetsWeb function
Loads the JavaScript AES-GCM implementation from the plugin's assets into the DOM.
This function injects a <script> element containing the contents of
assets/aes_encryption_decryption.js into the <head> of the web document.
It checks if the script is already loaded using the ID 'aes-gcm-js' to avoid
re-injection.
This is required before calling encryptAesGcmWeb or decryptAesGcmWeb.
Implementation
Future<void> loadJsFromAssetsWeb() async {
// Check if script is already added
if (document.getElementById('aes-gcm-js') != null) return;
String pluginPath = "packages/aes_gcm_crypto/";
String jsCode = await rootBundle.loadString("${pluginPath}assets/aes_encryption_decryption.js");
ScriptElement script = ScriptElement()
..id = "aes-gcm-js"
..type = "text/javascript"
..text = jsCode;
document.head!.append(script);
}
