ScriptHtmlTagAttributes class Null safety

Class that represents the possible the <script> HTML attributes to be set used by InAppWebViewController.injectJavascriptFileFromUrl.

Constructors

ScriptHtmlTagAttributes({String type, 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.onerror for 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
