# Yew Google Material


```toml
yew-google-material = "0.0.8"
```
Please, open new issue on github if you notice any error or mistake!

`yew-google-material` is a very simple crate to use some of google materials and `https://fonts.google.com/`


Unfortunately a lot of crates with materials, icons for yew framework are depricated and use depricated javascript code.

Here I use only Rust code to add some design features for yew.  

Now only buttons, text fields and icons are available. 

Buttons and text fields are not the same as one in google material web, but very similar to them. 

## Icons

To use icons from `https://fonts.google.com/icons` you need to add some html inside 
```html
<head></head>
```

There are three types of icons. Add this if you want to use Outlined style of icons:
```html
<link rel="stylesheet" href="https://fonts.googleapis.com/css2?family=Material+Symbols+Outlined:opsz,wght,FILL,GRAD@20..48,100..700,0..1,-50..200" />
```
To use Rounded style of icons:
```html
<link rel="stylesheet" href="https://fonts.googleapis.com/css2?family=Material+Symbols+Rounded:opsz,wght,FILL,GRAD@20..48,100..700,0..1,-50..200" />
```
To use Sharp style of icons:
```html
<link rel="stylesheet" href="https://fonts.googleapis.com/css2?family=Material+Symbols+Sharp:opsz,wght,FILL,GRAD@20..48,100..700,0..1,-50..200" />
```
Then choose on of the icons in the catalog of https://fonts.google.com/icons, i.e. 'search', 'star', 'menu', etc. and see example below. 

### Examples

```html
<link rel="stylesheet" href="https://fonts.googleapis.com/css2?family=Material+Symbols+Outlined:opsz,wght,FILL,GRAD@20..48,100..700,0..1,-50..200" />
```
```rust
use yew::prelude::*;
use yew_google_material::prelude::*;

<GIcon 
    size="16px"
    transition="all 0.2s"
    icon="search" 
    icon_style={GIconStyle::Outlined} 
    fill=true
    wght="200"
    grade="0"
    opsz="24"
    color="#fff"
/>
```

Note, you that you can animate icon attributes with transition. The default value is "unset", but for animation it is recomended to set "all 0.2s" or as you wish.

Or you can add an icon with default options:
```html
<link rel="stylesheet" href="https://fonts.googleapis.com/css2?family=Material+Symbols+Outlined:opsz,wght,FILL,GRAD@20..48,100..700,0..1,-50..200" />
```
```rust
use yew::prelude::*;
use yew_google_material::prelude::*;

<GIcon 
    icon="star" 
    icon_style={GIconStyle::Outlined} 
/>
```

## Buttons

![image](/images/elevated_button.jpg)
>GButtonStyle::Elevated styled button with trailing icon

![image](/images/filled_button.jpg)
>GButtonStyle::Filled styled button

![image](/images/outlined_button.jpg)
>GButtonStyle::Outlined styled button

![image](/images/text_button.jpg)
>GButtonStyle::Text styled button

![image](/images/icon_button.jpg)
>GButtonStyle::Filled styled icon button

The key size attribute of button is `font_size` attribute. It bonds a lot of other sizes and has the default value 14px. 

GButton has a lot of attributes (and you can make something similar to FAB button via them), but only `id` are required.

Attention! You must set `label` and/or use icon to make your button readable! 

### Examples

```rust
use yew::prelude::*;
use yew_google_material::prelude::*;

<GButton 
id="use_g_button" 
label="Button" />
```

Also you can add icon with `has_icon` attribute. If so, you also need to set `icon_style` attribute together with stylesheet inside `<head></head>`(see GIcon docs). If you need trailing icon use `trailing_icon` with `true` together with `has_icon` attributes in GButton.
To adjust icon parameters use `fill`, `wght`, `grade`, `opsz` attributes as well as with GIcon.

Attention! The way to add icon in this version is different from v.0.0.7. 

```rust
use yew::prelude::*;
use yew_google_material::prelude::*;

<GButton 
id="login_button"  // requiered
label="Sign In"
style={GButtonStyle::Outlined}
label_color="#fff"
has_icon="login"                     // requiered to add icon
trailing_icon=true
icon_style={GIconStyle::Outlined}    // requiered to add icon
wght="400"                           // add it only for icon if you need it
/>
```
Attention! If you change icon size within button you can break the design. Probably then you need to adjust width and height. Do it with caution.

## TextFields

![image](/images/input_filled.jpg)
>Simple text input with GInputStyle::Filled style

![image](/images/input_outlined.jpg)
>GInputStyle::Outlined slyled input with leading icon and trailing button icon

The key size attribute of input field is `font_size`. It bonds a lot of other sizes of text field and has the default value 16px. 

GTextInput has a lot of attributes, but only `id`, onchange and `label` are required. Label here has the same role as placeholder. If you do not need label, add it with empty double quotes.

See the describtion of this attributes here: `https://material-web.dev/components/text-field/#api`

### Examples

```rust
use yew::prelude::*;
use yew_google_material::prelude::*;

let onchange_username = Callback::from(|username: AttrValue| {Msg::InputUsername(username)});

<GTextInput
id="username_text_login_name"
onchange={onchange_username} 
label="Имя пользователя" />
```

Also you can add leading and trailing GIcons, change style, change Event to InputEvent and do many other things via attributes in this way:

```rust
use yew::prelude::*;
use yew_google_material::prelude::*;

let search_input = Callback::from(|search_input: AttrValue| {Msg::Search(search_input)});

<GTextInput

    id="username_text_login_name"

    event={GInputEvent::OnInput}

    oninput={search_input} 
    has_leading_icon=true

    has_trailing_icon=true

    input_type="text" 

    supporting_text="text"

    label="Введите поисковый запрос" >
    <GIcon 
       icon="search" 
       leading_icon=true
       icon_style={GIconStyle::Outlined} 
    />
    <GIcon 
       icon="cancel" 
       trailing_icon=true
       icon_style={GIconStyle::Outlined} 
    />
</GTextInput>
```

If you need to add trailing button icon inside input field, instead of `GIcon` use `GButton` inside `<GTextInput></GTextInput>` with attributes:
`has_icon` (icon name from `fonts.google.com/icons`), `trailing_icon` (`true`), `parent` (`DependsOn::GTextInput`), `icon_style` (Outlined, Rounded or Sharp)

Do not use `label` attribute for `GButton` inside `GTextInput`!
```rust
use yew::prelude::*;
use yew_google_material::prelude::*;

let username_input = Callback::from(|username_input: AttrValue| {Msg::Username(username_input)});

<GTextInput

    id="username_text_login_name"

    onchange={username_input} 
    input_type="text" 

    has_trailing_icon=true

    supporting_text="text"

    label="Введите поисковый запрос" >
    <GButton 
        id="login_button"
        button_type="button"
        parent={DependsOn::GTextInput}      // required inside GTextInput
        style={GButtonStyle::Outlined}      // required for icon inside GButton
        label_color="#6750A4"
        has_icon="login"                    // required for icon inside GButton
        trailing_icon=true
        icon_style={GIconStyle::Outlined}   // required for icon inside GButton
    />
</GTextInput>
```
If you need leading button icon element inside GTextInput, just remove `trailing_icon` attribute from GButton, add `has_leading_icon=true` for `GTextInput` and remove `has_trailing_icon=true`. 
Attentin! It is recomended to use `button_type` attribute with `"button"`, or your button will be on its own inside `<form></form>` element.
