WKWebView でローカルファイルにアクセスできないとき

More than 1 year has passed since last update.

cordova-plugin-camera などで取得した画像を読み込もうとすると「Origin null is not allowed by Access-Control-Allow-Origin.」のようなエラーが発生することがある。

// エラーが発生するコード
let img = new Image()
img.crossOrigin = 'anonymous'
img.onload = () => {

}
img.src = /* ローカルから読み込んだファイルパス */

色々と試したがプラグインをインストールするだけで簡単に解決することができた。
