[v4.0.0-beta.7] NfcManager.mifareClassicHandlerAndroid.mifareClassicWriteBlock crashes because MIFARE_BLOCK_SIZE is undefined

[mi1ton-dprim]

Hello!
NfcManager.mifareClassicHandlerAndroid.mifareClassicWriteBlock throws [Error: data should be a non-empty Array[undefined] of integers (0 - 255)] .

I have to:

if (undefined === NativeModules.NfcManager.MIFARE_BLOCK_SIZE) {
NativeModules.NfcManager.MIFARE_BLOCK_SIZE = 16;
}
