when i make test in the emulator i had to delete '!' in tw_hd_wallet_impl.dart if (!TWMnemonicImpl.isValid(mnemonic)) throw Exception(["mnemonic is invalid"]); in my samsung A21 dont but the app is crashing in the two cases

I tried to import the proyect in the same level of the proyect folder and declarate it in pupspect like this

flutter_trust_wallet_core:
  path: ../flutter_trust_wallet_core

and work fine, but when i tried to create an address the app crash and trow a 'NULL POINT EXEPTION' from libTrustWalletCore.so

Add

    init {
        System.loadLibrary("TrustWalletCore")
    }

in you android project MainActivity.kt file

MainActivity.kt file will looks like

class MainActivity: FlutterActivity() {
    init {
        System.loadLibrary("TrustWalletCore")
    }
}

Add

    init {
        System.loadLibrary("TrustWalletCore")
    }

MainActivity.kt file will looks like

class MainActivity: FlutterActivity() {
    init {
        System.loadLibrary("TrustWalletCore")
    }
}

Yeah, i did all and the plugin can create a random seeds but cant create a new wallet from the same seeds in HDWallet.createWithMnemonic, always trows a invalid exeption

Using isValidWord method can get TRUE in the words from mnemonic but not in the complethe phrase, i use bip39 plugin to compare

FlutterTrustWalletCore.init();
String mnemonic = "horror select baby exile convince sunset outside vehicle write decade powder energy";
List<String> split = mnemonic.split(' ');

for (var element in split) {
  print((split.indexOf(element) + 1).toString() + ' ' + element + ' -> ' + Mnemonic.isValidWord(element).toString());
}

print('[TRUST PLUGIN] mnemonic -> ' + Mnemonic.isValid(mnemonic).toString());
print('[BIP39 PLUGIN] mnemonic -> ' + bip39.validateMnemonic(mnemonic).toString());

the console show this

1 horror -> true
2 select -> true
3 baby -> true
4 exile -> true
5 convince -> true
6 sunset -> true
7 outside -> true
8 vehicle -> true
9 write -> true
10 decade -> true
11 powder -> true
12 energy -> true
[TRUST PLUGIN] mnemonic -> false
[BIP39 PLUGIN] mnemonic -> true

[phamducmanh1989]

change static int TWMnemonicIsValid to static bool TWMnemonicIsValid and refactor all references of it

[weishirongzhen]

try again with new version of trustwallet core native lib
