ScriptHtmlTagAttributes class Null safety
Class that represents the possible the <script> HTML attributes to be set used by InAppWebViewController.injectJavascriptFileFromUrl.
Constructors
- ScriptHtmlTagAttributes({String type = "text/javascript", String? id, bool? async, bool? defer, CrossOrigin? crossOrigin, String? integrity, bool? noModule, String? nonce, ReferrerPolicy? referrerPolicy, dynamic onLoad()?, dynamic onError()?})
Properties
- async ↔ bool?
-
For classic scripts, if the async attribute is present,
then the classic script will be fetched in parallel to parsing and evaluated as soon as it is available.
read / write
- crossOrigin ↔ CrossOrigin?
-
Normal script elements pass minimal information to the
window.onerrorfor scripts which do not pass the standard CORS checks. To allow error logging for sites which use a separate domain for static media, use this attribute.read / write - defer ↔ bool?
-
This Boolean attribute is set to indicate to a browser that the script is meant to be executed after the document has been parsed, but before firing
DOMContentLoaded.read / write - hashCode → int
-
The hash code for this object.
read-only, inherited
- id ↔ String?
-
The HTML id attribute is used to specify a unique id for the
<script>HTML element.read / write - integrity ↔ String?
-
This attribute contains inline metadata that a user agent can use to verify that a fetched resource has been delivered free of unexpected manipulation.
read / write
- noModule ↔ bool?
-
This Boolean attribute is set to indicate that the script should not be executed in browsers that support ES2015 modules — in effect,
this can be used to serve fallback scripts to older browsers that do not support modular JavaScript code.
read / write
- nonce ↔ String?
-
A cryptographic nonce (number used once) to whitelist scripts in a script-src Content-Security-Policy.
The server must generate a unique nonce value each time it transmits a policy.
It is critical to provide a nonce that cannot be guessed as bypassing a resource's policy is otherwise trivial.
read / write
- onError ↔ (dynamic Function?()?)
-
Represents a callback function that will be called if an error occurred while trying to load the script.
read / write
- onLoad ↔ (dynamic Function?()?)
-
Represents a callback function that will be called as soon as the script has been loaded successfully.
read / write
- referrerPolicy ↔ ReferrerPolicy?
-
Indicates which referrer to send when fetching the script, or resources fetched by the script.
read / write
- runtimeType → Type
-
A representation of the runtime type of the object.
read-only, inherited
- type ↔ String
-
This attribute indicates the type of script represented. The value of this attribute will be in one of the following categories.
The default value is
text/javascript.read / write
