Adds a loading state to stickers, so that a loading indicator appears while the sticker is being downloaded from IPFS.
In the case of a network failure or timetout, a reload button is shown instead. Once network is restored and the reload button is clicked, the image is reloaded from the network, going through the same lifecycle of showing the loading state first.
These components are used to render the chat info in the top bar of the chat view.
`StatusChatInfoButton` is an clickable button that will open chat info dialogs.
Closes#923
This component introduces `StatusLetterIdenticon`, `StatusImageIdenticon`
and `StatusIdenticon`.
- `StatusLetterIdenticon` renders an identicon with a single letter based on a
name.
- `StatusImageIdenticon` renders an actual image based on an identicon URL
- `StatusIdenticon` is a composition of the former both, but with a loading mechanism
to decide which should be rendered
The commit also ensures all of these components are used respectively throughout
the application.
Currently, exceptions thrown during transactions or gas estimation that were spawned in another thread are not being propagated, due to a limitation in nim (see https://nim-lang.org/docs/manual_experimental.html#parallel-amp-spawn).
This means any exceptions from status-go were not propagated correctly and would cause the app to crash. This includes entering the wrong password when trying to send a transaction.
The issue was addressed by passing a `success` variable by reference, which is set to false if an exception was thrown by status-go.
The problem was that the BigInt lib did not handle decimals at all. `divMod` only let the remainder be what is after the dot. So I created my own divde and multiply methods to move the dot depending on the number of decimals
