Aurum · Cloud Backup
Aurum · Cloud Backup is a production-ready Web3 Flutter screen from FlutterKit — free, with full source code.
A dark, Binance-styled (amber #F0B90B on near-black) Web3 screen for storing an encrypted copy of a wallet's recovery phrase to the cloud. The header "Encrypted cloud backup" sits below a circular back button, with a subtitle noting only the user's password can unlock it. A "Destination" group offers two selectable tiles: iCloud Keychain (masked r****@icloud.com) and Google Drive ("Connect a Google account"), each with a tinted icon chip and custom radio, the active tile ringed amber. An "Encryption password" field has a lock icon and visibility toggle; typing drives a four-segment strength meter labelled Too weak / Weak / Fair / Strong / Excellent from length, mixed case, digits and symbols. An amber key-icon warning card states a forgotten password makes the backup unrecoverable, with no reset. The pinned "Create encrypted backup" CTA stays grey until strength hits at least 3. Pure Flutter: bundled Inter font, forced dark Theme, custom radio and meter widgets, no plugins; destination choice and backup creation are exposed via onBackUp and onBack callbacks for any backend.
