解决flutter webview在iOS模拟器中输入框不能输入的问题

在ios > Runner > AppDelegate.swift中添加以下代码即可：

extension FlutterViewController {
    open override func pressesBegan(_ presses: Set<UIPress>, with event: UIPressesEvent?) {
        super.pressesBegan(presses, with: event)
    }

    open override func pressesEnded(_ presses: Set<UIPress>, with event: UIPressesEvent?) {
        super.pressesEnded(presses, with: event)
    }

    open override func pressesCancelled(_ presses: Set<UIPress>, with event: UIPressesEvent?) {
        super.pressesCancelled(presses, with: event)
    }
}
