Project description:
"I need a seasoned Flutter developer to craft a custom TextField-style widget that never leaves sensitive input—passwords, personal data, card numbers—sitting in memory as readable strings. The solution must drop smoothly into any existing Form widget, follow Flutter’s design conventions, and respect current best practices around in-memory data protection on both Android and iOS.

The core requirement is that at every point in the widget lifecycle the raw characters are either encrypted, zeroed out immediately after use, or held only in platform-level secure constructs. If you need to reach platform channels to achieve this, that is fine as long as the public Dart API stays simple for the rest of the app: developers should be able to replace a regular TextField with SecureTextField, pass the same parameters, and benefit from the protection automatically.

To make hand-off crystal-clear, I’ll consider the job complete when you provide:
• Full Dart source plus any native code or plugins you introduce
• A minimal demo app showing the widget wired into a standard login form
If you have prior experience shipping secure input fields or know specific OS-level APIs that harden in-memory storage, mention it in your proposal—those insights will weigh heavily in my selection." (client-provided description)
