ThemedAvatarPicker(
labelText: context.i18n.t('entity.avatar'),
value: avatarBase64,
errors: context.getErrors(key: 'avatar'),
onChanged: (value) {
avatarBase64 = value;
if (context.mounted) onChanged.call();
},
)
onChanged fires with a "data:<mimeType>;base64,<data>" string on selection, or null when cleared.disabled: true shows a lock icon and prevents opening the picker.customChild wraps any widget in an InkWell that opens the picker.label / labelText must be set — assert enforced.// With custom child trigger
ThemedAvatarPicker(
labelText: context.i18n.t('entity.avatar'),
value: avatarBase64,
customChild: CircleAvatar(
backgroundImage: avatarBase64 != null ? NetworkImage(avatarBase64!) : null,
child: avatarBase64 == null ? const Icon(Icons.person) : null,
),
onChanged: (value) {
avatarBase64 = value;
if (context.mounted) onChanged.call();
},
)
// Disabled
ThemedAvatarPicker(
labelText: context.i18n.t('entity.avatar'),
value: avatarBase64,
disabled: true,
)
onChanged with if (context.mounted) before calling the parent callback.context.i18n.t('entity.fieldName') for labelText — never hardcode strings.errors: context.getErrors(key: 'fieldName').const SizedBox(height: 10).
