Integrate with Slope Wallet (Mobile)
- 1.Mobile applications and wallets are pulling up and passing references to each other using the URL scheme method.
- 2.If the android device cannot pull up the other applications, you need to add the package name of the other applications to your AndroidManifest.xml.

Mobile application transaction request code example
String _strWalletSchemeUrl =
'slopewallet://wallet.slope/pay?returnSchemes=';
String _strMySchemeUrl = 'slopedapp://slope.dapp/pay?slopePayReturn';
void _send({Type type = Type.pay}) {
if (_adrsCtrl.text.isEmpty || _amountCtrl.text.isEmpty) return;
Map<String, dynamic> params = Map();
params['type'] = (Type.pay == type) ? 'pay' : 'connect';
if (Type.pay == type) {
params['address'] = _adrsCtrl.text;
params['amount'] = _amountCtrl.text;
params['memo'] = _memoCtrl.text;
if (_symbolCtrl.text.isNotEmpty) params['symbol'] = _symbolCtrl.text;
if (_titleCtrl.text.isNotEmpty) params['label'] = _titleCtrl.text;
if (_msgCtrl.text.isNotEmpty) params['message'] = _msgCtrl.text;
}
String strEnParams = convert.jsonEncode(params);
String strCovertParams = _covertString(strInput: strEnParams);
String strMyEncodeScheme = _covertString(strInput: _strMySchemeUrl);
String strDecodeParam = Uri.encodeComponent(strCovertParams);
_strSendScheme = _strWalletSchemeUrl +
strMyEncodeScheme +
'&slopePayParams=' +
strDecodeParam;
_launchURL(context, _strSendScheme);
}
Wallet transaction signature code example
String baseUrl = 'slopewallet://wallet.slope/pay?';
String oriUrl = uri?.toString().toLowerCase() ?? '';
if (false == oriUrl.startsWith(baseUrl)) return;
// prase scheme
String? strRetScheme = uri?.queryParameters['returnSchemes'];
if (null == strRetScheme || strRetScheme is! String) return;
if (strRetScheme.isEmpty) return;
var decodeScheme = hex.decode(strRetScheme);
var strScheme = utf8.decode(decodeScheme);
strRetScheme = strScheme.toString();
// prase params
String? strOriParam = uri?.queryParameters['slopePayParams'];
if (null == strOriParam || strOriParam is! String) return;
String strOriParamCom = Uri.decodeComponent(strOriParam);
var decode = hex.decode(strOriParamCom);
var strParam = utf8.decode(decode);
logger.d('pay param：$strParam');
var json = convert.jsonDecode(strParam);
SchemeModel model = SchemeModel.fromJson(json);
WalletEntity? wallet = context.read<WalletMainModel>().currentWallet;
if (null == wallet) return;
model.urlScheme = strRetScheme;
Once the mobile applications pulls up the wallet and sends the transaction information, it indicates that the user has allowed the native wallet application to sign and send the transaction to the chain.
dynamic siginTx = await WalletMainModel().approve(
privateKey: prKey,
sourceAddress: coinFind.splAddress,
sendAddress: model.address,
mintAddressSend: mintAddress,
amount: model.amount.toString(),
);
if (siginTx is String && siginTx.isEmpty) {
if (showing) Navigator.pop(context);
logger.d('Token no exist $siginTx');
return;
}
String strRet = await WalletMainModel().push(siginTx);
String strScheme =
model.urlScheme + '=$strRet' + '&type=${model.type, model.memo}';
