CrossmintExportPrivateKeyButton class

Export private key button matching the official Crossmint RN SDK ExportPrivateKeyButton component.

Only renders when wallet.canExportPrivateKey is true (email/phone signers). Returns SizedBox.shrink otherwise.

Headless consumers can supply a childBuilder to swap the Material default button for their own widget while keeping the eligibility check and loading state management. Pure-headless consumers can bypass this widget entirely and call wallet.exportPrivateKey() directly from their own button.

Properties

childBuilder → CrossmintExportPrivateKeyButtonBuilder?
Optional builder for the button visual. When null, falls back to the React Native parity Material OutlinedButton with a themed CircularProgressIndicator while the export is in flight. When non-null, the builder is invoked whenever the wallet is eligible to export and receives the current isLoading flag plus an onExport callback that the consumer wires to their own tap target. The onExport callback is null while loading so consumers can disable their button directly without a separate mounted check.
