Hi everyone as i just started to learn dart and flutter and trying to get access data from firebase. I have data in following formats in firebase. Now I want to access this data with the help of model and provider in dart & flutter. please someone help me to do this. I try multiple times but did not get it.

I need to use SharedArrayBuffer for a specific page, so I put this in next.config.js:
async headers() {
return [
{
source: '/upload',
headers: [
{
key: 'Cross-Origin-Embedder-Policy',
value: 'require-corp',
},
{
key: 'Cross-Origin-Opener-Policy',
value: 'same-origin',
},
],
},
]
},
The problem is, this only works when I go to the page and I do a refresh.
I want to filter my table data by createdAt,status_invitor and status_invited. I write query Like this
const query = qs.stringify({
filters: {
$and: {
createdAt: { $gte: firstDayOfTheMonth },
createdAt: { $lt: lastDayOfTheMonth },
},
$and: {
status_invitor: statusFilter
},
status_invited: statusFilter,
},
});
but is not working correctly
The filters are combined by default so unless I have misunderstood what you are trying to achieve, you don't need to use the $and operator.
const query = qs.stringify({
filters: {
createdAt: { $gte: firstDayOfTheMonth },
createdAt: { $lt: lastDayOfTheMonth },
status_invitor: statusFilter,
status_invited: statusFilter,
},
});
If you do want to mix AND and OR filters then you need to specify an array. You can see examples of that here: https://docs.strapi.io/developer-docs/latest/developer-resources/database-apis-reference/rest/filtering-locale-publication.html#complex-filtering
I'm working on a project where I wanted to query more than one field with a search term. This is the code I used to get it working. I think all you need to do is change the $or for the $and and it should work.
const query = qs.stringify( {
filters: {
$or: [
{ name: { $contains: term }},
{ venue: { $contains: term } },
{ performers: { $contains: term } },
{ description: { $contains: term } },
],
},
},
)
As explained in the NextJs documentation: https://nextjs.org/docs/api-reference/next.config.js/headers , it is possible to configure the HTTP headers of a page using the code below, however my code is not working.
Next Example:
module.exports = {
async headers() {
return [
{
source: '/about',
headers: [
{
key: 'x-custom-header',
value: 'my custom header value',
},
{
key: 'x-another-custom-header',
value: 'my other custom header value',
},
],
},
]
},
}
My Code:
module.exports = {
async headers() {
return [
{
source: '/about',
headers: [
{
key: 'cache-control',
value: 'max-age=31536000',
},
],
},
]
},
}
First of all, I tried to write how to save users input data to google sheet after developing the simple codes. It's able to work. Thank Mr.Master for providing this tutorial(Below the link).
Reference Mr.Master: https://www.youtube.com/watch?v=huwUpJZsTok
Next, I bumped into the problem below the code. I didn't know how to write it in Fulfillment. Could someone realize it to teach me?
Tool: Dialogflow, Google sheet, Firebase.
Theme: Order process
I tried to write Forhere() there. However, it didn't work.(First code)
function Forhere(agent){
const{
forhere, howmanypeople, whattime, namelist
} = agent.parameters;
const data1 = [{
Forhere: forhere,
HowManyPeople: howmanypeople,
Time: whattime,
Name: namelist
}];
axios.post('......', data1);
}
{/*....This code is a result of test(second one)

You can use below code
let forhere= agent.parameters.forhere;
let howmanypeople= agent.parameters.howmanypeople;
let whattime= agent.parameters.whattime;
let namelist= agent.parameters.namelist;
then use this variables in your api call.

Dialogflowfirebasefulfillment&Error message:
Although I think this error didn't show where these mistakes are.

Furthermore, I've write below the code worked formally(input users data to google sheet).
enter image description here
I'm using an Arduino with an ESP8266-01 module to upload a value to a Cloud Firestore database using the createDocument API with the following payload:
{
"fields": {
"distance": {
"integerValue": "555"
}
}
}
I do a POST-request to a route like this:
https://firestore.googleapis.com/v1beta1/projects/<MY_PROJECT>/databases/(default)/documents/<SOME_COLLECTION>?key=MY_VERY_SECRET_KEY
That all works, but I would like to add the server timestamp as well. I've found a few answers here on stackoverflow, but I have not been able to make any of them work.
How can I add the server timestamp to the created document? What I want is for the following to be created:
{
"fields": {
"distance": {
"integerValue": "555"
},
"timestamp" : {
"DATETIME": SERVER_TIMESTAMP
}
}
}
Any help appreciated.
What I ended up doing in the end was the following:
A POST request to a route like this:
https://firestore.googleapis.com/v1beta1/projects/<MY_PROJECT>/databases/(default)/documents:commit?&key=<MY_VERY_SECRET_KEY>
With the following payload:
{
"writes": [
{
"update": {
"name": "projects/<MY_PROJECT>/databases/(default)/documents/<COLLECTION_ID>/<DOCUMENT_ID>",
"fields": {
"distance": {
"integerValue": "555"
}
}
}
},
{
"transform": {
"document": "projects/<MY_PROJECT>/databases/(default)/documents/<COLLECTION_ID>/<DOCUMENT_ID>",
"fieldTransforms": [
{
"fieldPath": "servertime",
"setToServerValue": "REQUEST_TIME"
}
]
}
}
]
}
Where I generate a new DOCUMENT_ID (e.g. a GUID) instead of having cloud firestore generate one for me.
