A Small Dart package with Common Helpers


Small package with common utils. A library for Dart developers.


A simple usage example:

import 'package:dotup_dart_utils/dotup_dart_utils.dart';

main() {
  // TODO



flutter pub add dotup_dart_utils


dotup_dart_utils on pub.dev

Other widgets on pub.dev

Other open source flutter projects on Github

Use this package as a library

Depend on it

Run this command:

With Dart:

 $ dart pub add dotup_dart_utils

With Flutter:

 $ flutter pub add dotup_dart_utils

This will add a line like this to your package's pubspec.yaml (and run an implicit dart pub get):

  dotup_dart_utils: ^0.1.0

Alternatively, your editor might support dart pub get or flutter pub get. Check the docs for your editor to learn more.

Import it

Now in your Dart code, you can use:

import 'package:dotup_dart_utils/dotup_dart_utils.dart';


import 'package:dotup_dart_utils/dotup_dart_utils.dart';

void main() {
  // var awesome = Awesome();
  // print('awesome: ${awesome.isAwesome}');

What is dART Insurance (dART) | What is dART Insurance token | What is dART token

In this article, we’ll discuss information about the dART Insurance project and dART token

About dART

dART is the first NFT insurance platform on the market, preparing to launch on Binance Smart Chain’s intuitive and highly active network. With NFTs generating hundreds of millions of dollars of monthly trading volume, we provide a way for users to protect their valuable digital assets, which can regularly surpass seven or eight-figure sums.

By innovating on the traditional insurance model and introducing bonus features through the use of blockchain technology, dART will be able to reward platform stakeholders while providing safe, verifiable, and straightforward insurance coverage to this rapidly expanding digital marketplace.

dART users will secure insurance for their assets directly from the dART terminal, and our solution will be integrated into the NFT marketplaces.

The ability to insure NFT assets will become easily accessible to all crypto users. As the value being held in NFTs continues to grow, the ability to protect against risks becomes essential. dART will be the first platform allowing its users to insure their NFT assets.

NFTs are rapidly expanding, growing from a relatively obscure market to generating hundreds of millions of dollars in monthly trading volume. With the NFT market’s continuous growth, already valued at approximately $250 million at the end of 2020, dART is introducing the first platform built to protect against exploitation and hacks of NFTs through the utilisation of a decentralised insurance protocol.

The NFT market has begun to cement itself as a major player within the cryptocurrency space, but not a single NFT platform has incorporated a risk coverage solution for its users. We will be the first platform to address this, providing everyone a safe and secure ownership experience.

Using Insurance to Protect Your NFTs

If you’re reading this, you’ve probably heard of Beeple’s $69 million NFT sale through Christie’s Auction House, CryptoPunks worth millions of dollars each, and the countless other art pieces and digital collectibles that are worth five, six, or seven-figure sums. Considering these rare and highly sought-after pieces command incredibly high prices, it doesn’t make sense to leave them unprotected and uninsured.

Regardless of the sector, whether it be art, real estate, sports cards, or something more niche, any intelligent investor should take out an insurance policy to limit their downside risk. This rings especially true for decentralized markets, as there is a lot less accountability available if a problem arises and there is no centralized party to help resolve it. This is where dART comes in, offering NFT owners peace of mind through our user-centric platform.

Why Do NFTs Need Protection?

NFT protection should be at the forefront of any investor, speculator, or collector’s mind. There is a famous idiom in the blockchain community, “not your keys, not your coins”, with this also remaining true for any tokenized digital asset.

Even NFT platforms that offer their users the ability to store NFTs on a non-native wallet like Metamask present major risks, as hot wallets connected to the internet always have potential vulnerabilities. In the event that the NFT storage platform is compromised, if you accidentally download a virus, or if you experience an exploitation resulting in the loss of your asset, you need risk coverage. dART provides straightforward options with the sole goal of financially empowering NFT owners, picking up the slack that NFT platforms are unwilling or unable to offer their user bases.

All-in-all, if you have any form of significant wealth tied up in NFTs, whether that be hundred, thousands, or millions of dollars, asset insurance is the only way to truly protect yourself in this decentralised economy. Many have made life-changing money through their NFT collections and investments; they are at risk of losing everything they’ve worked for with zero repercussions if they do not take the proper safety precautions. As NFTs continue to establish themselves as a true value-generating asset and store of wealth on par with traditional physical art and collectibles, dART provides the key to make sure they are safe, with their value always accessible to the owner regardless of circumstances.

dART Token

As non-fungible tokens (NFTs) continue to establish themselves within the mainstream and climb in value, users need to be more proactive in protecting their digital assets. This is especially true within a decentralised economy with little accountability; if something goes wrong in the current marketplace, there is not much that anyone can do to provide protection. With this problem in mind, we developed dART, the first platform that allows users to protect the monetary value of their NFTs perpetually.

To act as an incentivization and governance mechanism for our decentralised network, we have created the dART token, the native cryptocurrency for our NFT risk coverage platform. dART will act as the ‘gas’ that facilitates transactions on our network, allow users to vote on the future direction of the platform, and earn through staking. Combining this with the token’s pre-programmed and limited scarcity, dART could have a tremendous impact on the NFT industry.


Third-party insurance companies compose themselves to generate as much profit as possible, even if it’s at the expense of their users; at dART, we are taking a different approach. With a focus on creating a highly functional decentralised and distributed risk coverage network, we are collectively determining the future direction of the platform through our community, relying on democratic principles to guide us forward. All dART holders will have a say in direct proportion to their ownership stake in the network, allowing for a fair and equally representative decision-making process.

Staking and Earning Fees

Beyond governance, dART introduces passive income opportunities directly to token holders. Any user will be able to easily stake dART in liquidity pools, generating a high and reliable APY, as well as stake the LP tokens generated into our governance staking protocol. Through these implementations, we are enabling easy-to-access reward pools where anyone can earn staking and LP rewards in proportion to their share of the staking pool.

The staking of dART in liquidity pools allows us to provide discretionary risk coverage to NFT holders, forming a buffer against losses due to hacks or manipulations. While the tokens acting as insurance collateral are sitting idly in the pool, they will be distributed amongst dART defi partners, who will use the liquidity to generate yield for dART owners. This model mirrors how the traditional insurance ecosystem works, but instead of the profits lining the pockets of wealthy executives and shareholders, they are returned back to the users of the platform, rewarding them alongside the platform’s growth and success.
