I have been working on a flutter project for a while now, but I had to change the PC I am using for some reasons. the thing is that every time I try to run the app I get bunch of errors then the app crashes and the connection get lost. I tried to run the app from the old PC again and It worked fine.
This is the stack of errors I get before the crash:

Anyone have any idea of what is going on here?
Thanks in advance.
Are you sure you have the same version of flutter as the computer you are using? You can check this thread

I have a problem when running a tflite model in my image classification app project( flutter ).
I have converted my CNN model to a tflite model via the code below:
import tensorflow as tf
converter = tf.lite.TFLiteConverter.from_saved_model('/content/drive/MyDrive/CNN_Model/10.07.CNNmodel.100.92')
# converter.optimizations = [tf.lite.Optimize.OPTIMIZE_FOR_LATENCY]
converter.target_spec.supported_ops = [
tf.lite.OpsSet.TFLITE_BUILTINS, # enable TensorFlow Lite ops.
tf.lite.OpsSet.SELECT_TF_OPS # enable TensorFlow ops.
]
tflite_model = converter.convert()
open("converted_model.tflite", "wb").write(tflite_model)
I tested the output of the tflite model and believe that it was converted successful. But when I added to my dart file in my project by the code:
Future loadModel() async {
await Tflite.loadModel(
model: 'assets/tflite/converted_model.tflite',
labels: 'assets/tflite/labels.txt',
);
}
After I ran the main.dart, took a picture to test, I got these errors:

When I removed the Normalization layer in my CNN model then converted it again, the app runs smoothly. But removing Normalization model decreased lots of my model accuracy.
I'm new to flutter. By any chance, has anybody encountered and resolved this before? Thanks for spending time.
dependencies {
implementation 'org.tensorflow:tensorflow-lite:0.0.0-nightly-SNAPSHOT'
// This dependency adds the necessary TF op support.
implementation 'org.tensorflow:tensorflow-lite-select-tf-ops:0.0.0-nightly-SNAPSHOT'
}
The converted model contains the Select TF ops. This means the model requires the Select TF op dependency.
If the above dependency is too big footprint, please consider creating a custom AAR through the selective build https://www.tensorflow.org/lite/guide/reduce_binary_size
See also https://www.tensorflow.org/lite/guide/ops_select.
Having a weird issue and cant seem to figure out if I have something setup wrong (new with Providers and streams) or if its a bug. Everything seems to work fine except when the app resumes after being backed out with the back button, on Android, and then restarted. Steps to reproduce:
Launch App
hit back button to close app (not just minimize)
Relaunch app
I get the following error:

After a lot of debugging and trying to figure out what was causing it. Ive narrow the problem down to StreamProvider and my user data. In my main screen I load a stream of the Users data with this:
return FutureProvider.value(
value: Provider.of<IAPProvider>(context).initialize(),
child: StreamProvider<User>.value(
value: DatabaseProvider().streamUser(user.uid),
child: MainScreen(),
),
);
And the code for the stream is this:
Stream<User> streamUser(String id) {
return Firestore.instance
.collection(USER_COLLECTION)
.document(id)
.snapshots()
.map((snap) => User.fromFirestore(snap));
}
I figured out that anytime I try to write to the User document on the cloud firestore database the app crashes, but only when I have done the steps above. On the initial launch (and works fine if I relaunch after it crashes) everything works as expected. Something like this:
Firestore.instance.collection(USER_COLLECTION).document(user.uid).updateData({'last_login': FieldValue.serverTimestamp()});
I have just published my first app today but for some reason when I use the published version I keep getting a ClassNotFoundException error when it starts up. It works fine when I test it in debug mode on my phone so I'm not sure whats causing this.
