My question is while we are working with firebase in flutter, updating something to its newer version is important? Or how much is it important, if it is?

I mean, If I don't update the code just like above (highlighted with yellow line ), it cause an error?

@Aashishm178

No it will not cause any error or problem

Is anyone aware of a method of doing autocomplete with flutter web? Seems there is a bug in all of the packages where it doesn't allow a user to select anything

Mayank Janmejay

@mayankjanmejay

@Omega_Primus_twitter are you able to make http post requests on flutter web?

Omega Prime

@Omega_Primus_twitter

not yet, that was stage 2, i am just working with local data right now

is that also buggy then?

@mayankjanmejay forgot to tag you

Mayank Janmejay

@mayankjanmejay

Yea, i built a app using firebase and google firestore. That with flutter works perfectly on android and web but now i am trying to move the data source to a different api and i cant do simple post get requests.

Autofill has been rather buggy in my tests, hopefully someone else has had better luck with it

@Omega_Primus_twitter I have 3 android apps with flutter, i tried porting 1 to web and after not great success i am thinking of ditching the framework for web.

Omega Prime

@Omega_Primus_twitter

@mayankjanmejay Hmm, i hope it doesn't have issues, I had spent a good bit of time on my app. I will give it a go then, I was just going to use wiki for now as an autocomplete example as there is a lot of data from it https://en.wikipedia.org/w/api.php?action=opensearch&search=$query&limit=20&format=json

I have columns 2 children: listview (reversed) and a container
I want the listview to start at the top though. how can I do that?

Naveen yadav

@naveenyadav15

@matanshukry FIrst define the container and then define listview respectively in column children

Matan Shukry

@matanshukry

@naveenyadav15 What container are you talking about? the issue is the listview is reversed, so the content starts from bottom

Naveen yadav

@naveenyadav15

okay i understood now so a workaround is you reverse the items list rather than reversing the listview

Matan Shukry

@matanshukry

I'm reversing the listview because of scrollling not because of the content, so I can't do that either

Naveen yadav

Hi all,
I updated android studio with flutter and dart plugin but when running the application get stuck with emulator always says:
"Emulator: Warning: Quick Boot / Snapshots not supported on this machine. A CPU with EPT + UG features is currently needed. We will address this in a future release."
Please suggest how this can resolve. System configuration is 64bit Core2Duo Processor with enabled Virtualization and UEFI from BIOS, but the same red line appears in android studio Event Log.

Hi all, I was able to make a flutter ffi plugin run with the generated example project on iOS, but when doing so on Android, I seem to have JDK/gradle configuration issues, such as the following in my MainActivity.kt

Check your module classpath for missing or conflicting dependencies
Error running 'libmynative': No JDK specified for module 'mynative_example_android'
Cannot access 'android.app.Activity' which is a supertype of 'com.my.app'. Check your module classpath or conflicting dependencies

How should I go about this?

I do have the following dependencies specified in my build.gradle for the Android example app

dependencies {
implementation fileTree(dir: 'libs', include: ['*.jar'])
implementation "org.jetbrains.kotlin:kotlin-stdlib-jdk7:$kotlin_version"
implementation 'androidx.appcompat:appcompat:1.0.2'
implementation 'androidx.core:core-ktx:1.0.2'
implementation 'androidx.constraintlayout:constraintlayout:1.1.3'
testImplementation 'junit:junit:4.12'
androidTestImplementation 'androidx.test.ext:junit:1.1.0'
androidTestImplementation 'androidx.test.espresso:espresso-core:3.1.1'
}

So I assume that the system will find the JDK for me. On the other hand, I built another kotlin/NDK Android project, with the same version of Android Studio 3.6.3, which runs perfectly. I basically copied most Gradle settings from there.

// You can use whatever duration and curve you like
setState(() {

}

void onPageChanged(int page) {
setState(() {
this._page = page;
