Contribute

This app was built with several repos, developers of other substrate based chain
may create their own plugin and put it into polkawallet app:

__ polkawallet-io/app
    |
    |__ polkawallet-io/ui
    |    |__ polkawallet-io/sdk
    |
    |__ polkawallet_plugin_kusama
    |    |__ polkawallet-io/sdk
    |    |__ polkawallet-io/ui
    |
    |__ polkawallet_plugin_acala
    |    |__ polkawallet-io/sdk
    |    |__ polkawallet-io/ui
    |
    |__ polkawallet_plugin_laminar
    |    |__ polkawallet-io/sdk
    |    |__ polkawallet-io/ui

    |__ <...>

1. polkawallet-io/js_api

This is a polkadot-js/api wrapper which will be built into a single main.js file
to run in a hidden webView inside the App. So the App will connect to a substrate node
with polkadot-js.

And we wrapped polkadot-js/keyring in it, so the App can manage keyPairs.

2. polkawallet-io/sdk

This is a polkawallet-io/js_api wrapper dart package, it contains:

1. Keyring. Managing keyPairs.
2. PolkawalletSDK. Connect to remote node and call polkadot-js/api methods.
3. PolkawalletPlugin. A base plugin class, defined the data and life-circle methods
   which will be used in the App.

A polkawallet plugin can get users’ keyPairs in the App from Keyring instance.

A polkawallet plugin implementation should extend the PolkawalletPlugin class and
define it’s own data & life-circle methods.

3. polkawallet-io/ui

The common used flutter widgets for polkawallet-io/app, like:

• AddressInputForm
• TxConfirmPage
• ScanPage
• …

4. polkawallet-io/polkawallet_plugin_xxx

Examples:

1. polkawallet-io/polkawallet_plugin_kusama
2. polkawallet-io/polkawallet_plugin_acala
3. polkawallet-io/polkawallet_plugin_laminar

5. App state management

We use https://pub.dev/packages/mobx.
so the directories in a plugin looks like this:

__ lib
    |__ pages (the UI)
    |__ store (the MobX store)
    |__ service (the Actions fired by UI to mutate the store)
    |__ ...

6. Submit your plugin

While your plugin was finished and tested, you may submit an issue in this repo.
We will check into your plugin and add it into the App.

7. Plugin update

Submit a update request issue to update your plugin. There are two different kinds of update:

1. Update the dart package. We will rebuild the App and publish a new release.
2. Update the js code of your plugin (dart code was not affected). We will rebuild the
   js bundle file and the app will perform a hot-update through polkawallet-api.

Translation

Polkawallet App has several translation projects on crowdin.com:

• polkawallet
• kusama plugin
• acala plugin

Language files in the project are written in json-like style:

final enAccount = {
    'key': 'value',
    'key.another': 'Another value for translation.',
    'key.multiline': 'Multiline text are \n split with symbol \n.',
};

/// This 3 strings above will display in the App like:
// value

// Another value for translation.

// Multiline text are
// split with symbol
// .

You need to keep the 'key' field on the left as it is, and translate the 'value'
field on the right only. Note that the \n symbol split a long string into several lines.
