To get rid of that error you need to use the bang operator to tell the compiler that snapshot.data won't be null.

Flutter - How to refresh a Widget on button Click?

Asked 2022-Mar-01 at 10:15

I'm making an app where I plot charts of cryptocurrency. I have a file like this, that renders a chart of btc/24h in it. I'm using chart_sparkline package to plot the chart.

I have the following code, and it is not working on a button click, how do I fix this?

I fixed this, I was passing constructor parameters of Portfolio to _PortfolioState, this won't update the values the next time. Instead of passing these values to _PortfolioState, I used widget.coin and widget.days to extract the data from the Portfolio class.

It's all note : when you use function get_db_session in database.py like a generator, close function of session doesn't work as auto, so you should close them like manually. If you need more detail, send email, drr000t3r@gmail.com. Good Luck.

Mongoose get all documents where date and number of weeks have current date

I have this type of documents in mongoDB.

ANSWER

Answered 2022-Feb-17 at 08:39

You can use $dateAdd in an aggregation query like this:

Note here only is necessary a $match stage with $expr to get documents where:

Current date ($$NOW) is greater or equal than $start_date.
Current date ($$NOW) is lower or equal than calculated date adding X weeks.

i.e. the date found is between $start_date and start_date + X weeks.

Cannot perform a non-multi update on a time-series collection

Asked 2022-Feb-12 at 19:52

Hi I am using newly Timeseries mongodb collection. My mongodb version is 5.0.6. I am following this tutorial. I create a collection like this.

...

ANSWER

Answered 2022-Feb-12 at 19:52

Try adding { multi: true } config.

If you check the docs, there are still some limitations for updating time-series collections.

Update commands must meet the following requirements:

The query may only match on metaField field values.

The update command may only modify the metaField field value.

The update must be performed with an update document that contains only update operator expressions.

The update command may not limit the number of documents to be updated. You must use an update command with multi: true or the updateMany() method.

The update command may not set upsert: true.

How to programmatically validate Tether (TRC20) Wallet Addresses in PHP?

Asked 2022-Feb-09 at 10:38

I am having an issue related to validating cryptocurrency wallet addresses, specifically USDT.

USDT can be validated either as a BTC or ETH address, depending on the network type.

Basically it goes like that:

If cryptocurrency is USDT and chain type is ERC20, validate the address against ETH address format.
If cryptocurrency is USDT and wallet type is OMNI, validate the address against BTC address format.

I haven't managed to find a specific validation for USDT:TRC20 addresses and I am not sure how to validate them.

QUESTION

Add data into 2 columns in same row with the data coming from Javascipt Websocket

Asked 2022-Jan-17 at 05:28

I am new to JavaScript, not sure if this very basic question. I've created a Bitcoin Price update dashboard using the data fetched from the external WebSocket. I managed to get the data from the WebSocket and display it on the HTML table but i was only able to fetch only the live price of the bitcoin I want to also display the Bitcoin quantity in the other column. I want to know how to append two different data in 2 columns in one row. I tried my best to explain.

I have provided the code snippets below as well as external Websocket from where I am pulling the data.

NOTE: I'm pulling the data from an external websocket and with that WebSocket I can get all the details like Bitcoin price, quantity, type and everything. "messageObject.p" means Price and "messageObject.q" means Quantity. p=price and q=quantity. I'm able to get the messageObject.q (quantity) to be displayed on the table but I'm unable to show the messageObject.p (price) in the other column of the table.

Please let me know how should I insert the row dynamically into a HTML table. Thank you so much in advance

You only have one parameter in your insertRow() function. Also, inside of your insertRow() function, you are never trying to read from the passed in quantity variable.

Trying to plot multiple indexed prices of cryptocurrencies with different dates

Asked 2021-Dec-31 at 18:55

I'm trying to create a nice graph of indexed prices for a few currencies so I can track relative performance from origin for different projects and price-levels.

Below is my dummy code. I've tried a lot of things but this is as far as I got...

R plot of the orignal code: prices of HEX and BTC

I wish to add other currencies as I go along.

In the end it is just a data frame with multiple columns that all need to start on the same point, the timestamp is irrelevant and I could plot only the series or shift them all to start on the same location.

This is what I'm trying to achieve:

Indexed prices of projects starting at same origin
